Обсуждение: Perl DBD / DBI modules
I've recently compiled and put into service Posgresql v6.4. All is working well. I am looking for information on locating, compiling, and implementing a Perl DBD or DBI for Postgresql. Can anyone assist? Bob

I've used PostgreSQL before, but has just joined this mailing list again after having searched www.postgresql.org for any information about 6.4. There's no mention of what is news in 6.4 anywhere to be found. Why not? What _is_ new?

I studied the TODO list without finding these elements. How about including then on the TODO list ? 1. Better money types. As it is now, it is unusable for large amounts, because it really maps to an 4 byte integer. The best solution would be to make the size configurable, but maybe it could do to make it 8 byte integer? 2. An ALTER TABLE ALTER COLUMN new-type. Of course the will be a risk of loosing information here, but that's the users problem if he eg. want to convert a 50 character field to 30 character. On a related topic, how far down the list is the row level locking? Will it come in a not too distant release?

Vadim has already starting throwing in code for this...his plan is
for v6.5 release (~3months) for this to be in place...

Interesting...will this help out vacuuming any?

No. Vacuum will still exclusively lock relation. But I'll fix vacuum to unlock pg_class (when vacuuming all tables in database). And note - this will be not row level locking, but multi-version concurrency control. Vadim

TODO list has:
* Make MONEY/DECIMAL have a defined precision

Added:
* Add ALTER TABLE DROP/ALTER COLUMN feature

LLL in 6.5 doesn't include row level locking ? Thanks. Hiroshi Inoue Inoue@tpf.co.jp

One systems (Informix, Sybase) use locking for concurrency control, another ones (Oracle, Interbase) use multi-versioning for this. I'm implementing multi-version concurrency control. Vadim

What I meant was How writers block other writers in LLL ? Certainly readers block no writers(readers) in LLL. But writers block no writers or the same-row writers or the same-table writers ? Currently writers block the same-table writers(readers also) ? Thanks. Hiroshi Inoue Inoue@tpf.co.jp

Only same-row writers will be blocked. Vadim
Is there anyone working on XML integration? Services include: a) Import/Export to XML (DTD defines schema) b) Access (through stored procedures) to XML (PSAX anyone?) b) Emulated tables (that direct queries to XML queries)? c) Other fun XML items. :) Clark
Anyone working on Row level locking and on-line recovery? I have some ideas (and questions) in this area. Also, I was wondering if there is a "transaction server" project, i.e., a server that helps provide a consistent client interface to both the database and application servers. Thank you! Clark

row level loocking shoudl be in place for v6.5...not sure about
on-line recovery, but I *believe* Jan is working on redo-log support...

Ooh, is this the kind of log you can use for transaction
replication?
