Обсуждение: Beta1 announcement: alpha1 draft
Hello, Here is a alpha draft of the Beta1 announcement. I am aware it is not complete as I don't have release notes yet. PostgreSQL 9.6 Beta1 Released! The PostgreSQL Global Development Group announces today that the first beta release of PostgreSQL 9.6 is available for download. This is a feature freeze release and should contain all features and APIs which will be in the final release. Users should begin testing their applications against 9.6 Beta 1 in preparation for the final release. Major changes since 9.5 The 9.6 features several significant changes and exciting enhancements including: * Parallelism for certain queries (see max_parallel_degree) * Increased logical decoding features * Full Text Search improvements * Join Pushdown for postgres-fdw * Enable pg_dump ACL support In particular, the the parallelism feature should bring a noticeable increase in performance to supported queries. Beta Schedule This is first beta release of version 9.6, indicating that very few user-visible feature changes are expected before final release. The PostgreSQL Project will release additional betas as required for testing, followed by one or more release candidates, until the final release in late 2016. For further information please see: http://www.postgresql.org/docs/devel/static/release-9-5-2.html (Update to 9.6GBeta1) Notable upcoming community releases PgAdmin4 is in preview mode (insert link) PgLogical is available for testing (insert link) -- Command Prompt, Inc. http://the.postgres.company/ +1-503-667-4564 PostgreSQL Centered full stack support, consulting and development.

Sort pushdown is of less interest than join pushdown, but DML pushdown seems like a big deal. > * Enable pg_dump ACL support I'm not entirely sure anyone will know what this is or why they should care. It might be worth mentioning if we can clarify that. Also note we now have: Extension cascade support to install dependencies Cube extension kNN support Command progress reporting for VACUUM Detailed wait information in pg_stat_activity Frozen page data in visibility map for skipping vacuum on already-frozen data New remote_apply replication mode which waits for confirmation that a standby has applied changes Index-only scans for partial indexes Support for multiple synchronous standbys User-defined expiration of snapshots to control table bloat I think there are a decent number of people for whom the frozen page data in the visibility map will be a really big deal, even bigger than parallel query. And I think the combination of synchronous_commit=remote_apply and multiple synchronous standbys is also going to be really, really useful for anyone who wants to build a robust read-scaling cluster around PostgreSQL. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company

Agreed. Thanks! Stephen

And phase 2...
Note, I am purposely limiting the features we list to a maximum of 5.
This is just a beta announcement, we need people to read it and anything
longer than one page and we lose the majority of the audience.
PostgreSQL 9.6 Beta1 Released!
The PostgreSQL Global Development Group announces today that the first
beta release of PostgreSQL 9.6 is available for download. This is a
feature freeze release and should contain all features and APIs of the
final release. Users are encouraged to begin testing their applications
against this latest release.
Major changes since 9.5
The 9.6 features several significant changes and exciting enhancements
including:
* Parallel sequential scans, joins and aggregates
* Enhanced synchronous replication support with Support for multiple
synchronous standby and remote_apply confirmation.
* Phrase full text search
* Pushdown support for joins, DML (UPDATE/DELETE) and sorts for
postgres_fdw
* Frozen page data in visibility map for skipping vacuum on
already-frozen data
In particular, the the parallelism feature should bring a noticeable
increase in performance to supported queries.
Beta Schedule
This is first beta release of version 9.6, indicating that very few
user-visible feature changes are expected before final release. The
PostgreSQL Project will release additional betas as required for
testing, followed by one or more release candidates, until the final
release in late 2016. For further information please see:
* http://www.postgresql.org/docs/devel/static/release-9-5-2.html

Err, worse, that particular comment is just wrong- pg_dump has supported
dumping ACLs for a very long time, we're just now supporting dumping
ACLs for objects in pg_catalog (and objects which are members of
extensions) which are changed from their default.

Ugh that was indeed broken. Thanks for pointing it out - fixed now, and the slides are there.
JD, Thank you for kicking this off! I've created a wiki page based on the content from this thread, for better collaboration. https://wiki.postgresql.org/wiki/9.6betareleasedraft Changes I made: 1. adding template content from prior beta releases 2. rephrasing some features to try to make them clearer to casual users (this still needs help) 3. Noting that API/feature changes may still happen, because they may. In fact, we're pretty sure that we're at least changing a few GUC names. -- -- Josh Berkus Red Hat OSAS (any opinions are my own)

You changed the description of multiple synchronous standbys so that it now mentions only multiple synchronous standbys and omits all mention of synchronous_commit=remote_apply; JD's last version mentioned both. You changed the description of pushdown for FDW so that it no longer talks about direct updates, just sort and join pushdown. And you changed the description of the freeze map changes so that it's wildly inaccurate. I think the last version JD posted was much better. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company

If it is a product, yes but I do believe (within conservative reason) that highlighting upcoming stuff shows we collaborate. Granted it should never be "the reason" for the announcement but a little enthusiastic collaboration on cool Pg utilities? Heck yeah :) Logical decoding for users, is useless without PgLogical (right now). Why wouldn't we mention it? PgAdmin is *the default* GUI admin tool and version 4 is a major milestone, why wouldn't we mention it? PgBackrest is *the* most talked about backup utility we have, why wouldn't we help invigorate that community?

What would you suggest as an alternative? I exclusively speak to practitioners. The people doing the lifting after we release. A constant question is about tools. Heck, most of the time it isn't, "when will we support X", it is more, "what tool would help me do Y?"

I think there's a fine line between advocating good third-party projects and undue partisanship. If we advocate a bunch of Crunchy-developed tools and no 2ndQuadrant-developed tools, or visca versa, then people at the other company may not like that very much. Never mind what might be done by EnterpriseDB, Dalibo, PG Experts, and others. If we never recommend anything, that's not good, but favoring one company over another is not good either.

I don't agree with this. The version you posted shows a rather lackluster faith in our user base. Further, this is a *BETA* even if you are correct that your wording is better, the people that are going to be using/testing this version *ARE* the people who are going to research and know what those features are.

That isn't useful. Reasons: 1) It is the announcement for the Postgres core project. 2) Calling out projects is the community declaring winners and I don't we should be in that game. 3) It is an announcement and most folks quit reading after the first paragraph anyway. 4) It is a Beta announcement and the fact that the code is at that stage is enough of an incentive for those that care. > > > JD > > -- Adrian Klaver adrian.klaver@aklaver.com

If that is the communities will, so be it. No, you're correct. We should definitely use (and borderline abuse :>) every opportunity to highlight + encourage related Community projects. We're *on their side* after all, and want them to be successful. It's not hurting us in the slightest to do that. If someone feels that's picking favourites... tough. ;) Point out the alternatives, and we can mention them in the subsequent announcements. :D + Justin -- "My grandfather once told me that there are two kinds of people: those who work and those who take the credit.

That isn't useful. The above supplies reasons why. The other reason is that the beta draft, including a lot of stuff we NEED to have in there, is already something like 2 pages long. There's a limit to how much we can expect people to read; a list of accessory projects having releases at the bottom wouldn't get read.

Got a 1-sentence description? I think that what we want to convey is that you can now build read-scaling clusters using PostgreSQL that are actually reliable. synchronous_commit=remote_apply provides the reliability, because now you can guarantee that the data is visible on the remote nodes, not just in the queue to be applied. And the multiple synchronous standbys feature allows you to extend that guarantee to as many nodes as you've got. Now, how to phrase that in one sentence, I'm not quite sure. Maybe: * new synchronous replication features, making it possible to build reliable read-scaling clusters But that'd need some meat on the bones elsewhere. >> You changed the description of pushdown for FDW so that it no longer >> talks about direct updates, just sort and join pushdown. > > Probably direct updates should be its own line then. Suggested phrasing? I think it can maybe be all one line, like this: * allow postgres_fdw to push sorts, joins, UPDATEs, and DELETEs to remote servers The upshot is that, apart from particular features, people can expect postgres_fdw to deliver significantly better performance in a bunch of situations than it did before. Sadly, there wasn't time to get aggregate pushdown done for this release, or we would really have had something to boast about. But it's still a good story. >> And you >> changed the description of the freeze map changes so that it's wildly >> inaccurate. > > Again, "so WTH should I care if there's a freeze bit on the visibility > map?

Well, what you said is that freezing is more efficient. That presupposes that people know what freezing is. If they do, and they read that, they're going to think that the freezing itself happens faster, which isn't true. What we want them to understand is that we can skip repeatedly freezing the same stuff. So, you could say, for example: * avoid repeatedly freezing the same old data, decreasing the impact of autovacuum activity That uses no technical term that your version doesn't. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company

Not entirely sure I'm following along correctly, but if we're talking about tools being updated for 9.6, it seems likley that all of the backup tools which use pg_start/stop_backup will be updated for the new API.

Hi,

I think the mere fact that this discussion is occuring should be
indicative of this being a bad idea. In short, -1 from me.
I agree with Robert and Alvaro. While I generally think that promoting satellite projects/tools/products is strategic, I think the community should not favour any position, rather facilitate objective and super-partes promotion of such tools. This could be in the wiki or, why not, in the documentation itself.
However, I guess we need to reflect on the status of the Wiki (I blame myself too).

The changes are to pg_start/stop_backup and their updated definitions can be reviewed here: http://www.postgresql.org/docs/devel/static/functions-admin.html Note that it's technically backwards compatible, however, the existing exclusive backup approach is bad and may mean that the database doesn't automatically recover from a crash which happens while the backup is running. All backup tools should be updated to the new APIs to avoid that risk. Thanks! Stephen

No, it's not new. I'm not sure off-hand if it's documented.
It is not new.
And no it is at least not well documented. But there are other parts which aren't as well - such as the requirement to actually run pg_stop_backup() even in the case you want to abort a backup, or your next one will fail. Basically the old method is quite fragile and no, we haven't documented that properly previously.

Well, if the API was in wide use and will be supported for several more
years, we had better document it, no?
Absolutely. That was part of that "bigger backup docs rewrite" that hasn't happened yet, but hopefully will before the final release.

Well, I don't even know the details of the failures, so I can't add that

FYI, I'm not ignoring this request, I've just been insanely busy lately. I definitely plan to get it done, but I won't make it before beta (as should be obvious by now, given the timing). My apologies.

Point, although we use the phrase a lot elsewhere. Really "remote
execution" might be better, but we don't really use those words anywhere
else ...
postgres_fdw now executes sorts, joins, updates, and deletes on the remote server.
Though sort/join seems to be a different class than update/delete; possibly warranting two sentences.
Enhanced federated database support via postgres_fdw: you can now execute updates and deletes on the remote server. Furthermore, sorts and joins are now executed remotely, reducing data transfer and improving speed.
Though, for me, "push down" is lot less cumbersome than "enhancing federated database support"
The later sounds more geek than the former.
I could be a bit off as I haven't really delved into the feature. But I suspect any inaccuracy would be a fair trade for simplicity in this non-technical document.
