Commit b75f467b6e removed the LogicalTapeAssignReadBufferSize() function, but forgot to update this comment. The read buffer size is an argument to LogicalTapeRewindForRead() now. Doesn't seem worth going into the details in the file header comment, so remove the outdated sentence altogether. https://git.postgresql.org/pg/commitdiff/45f87b7710214ea71947ee3678c6b7cb61580797 Teodor Sigaev pushed: - Fix wrong validation of top-parent pointer during page deletion in Btree. After introducing usage of t_tid of inner or page high key for storing number of attributes of tuple, validation of tuple's ItemPointer with ItemPointerIsValid becomes incorrect, it's need to validate only blocknumber of ItemPointer. Missing this causes a incorrect page deletion, fix that. Test is added. BTW, current contrib/amcheck doesn't fail on index corrupted by this way. Also introduce BTreeTupleGetTopParent/BTreeTupleSetTopParent macroses to improve code readability and to avoid possible confusion with page high key: high key is used to store top-parent link for branch to remove. Bug found by Michael Paquier, but bug doesn't exist in previous versions because t_tid was set to P_HIKEY.

Author: Liudmila Mantrova https://git.postgresql.org/pg/commitdiff/9975c128a1d1bd7e7366adf133b21540a2bc2450 - Make bms_prev_member work correctly with a 64 bit bitmapword. 5c067521 erroneously had coded bms_prev_member assuming that a bitmapword would always hold 32 bits and started it's search on what it thought was the highest 8-bits of the word. This was not the case if bitmapwords were 64 bits. In passing add a test to exercise this function a little. Previously there was no coverage at all. David Rowly https://git.postgresql.org/pg/commitdiff/a5ab8928d7d9e2cf76ed0590efbd9795ea9e5b5e - Add missing and dangling downlink checks to amcheck. When bt_index_parent_check() is called with the heapallindexed option, allocate a second Bloom filter to fingerprint block numbers that appear in the downlinks of internal pages. Use Bloom filter probes when walking the B-Tree to detect missing downlinks. This can detect subtle problems with page deletion/VACUUM, such as corruption caused by the bug just fixed in commit 6db4b499. The downlink Bloom filter is bound in size by work_mem. Its optimal size is typically far smaller than that of the regular heapallindexed Bloom filter, especially when the index has high fan-out.

This controls both plan-time and execution-time new-style partition pruning. While finer-grain control is possible (maybe using an enum GUC instead of boolean), there doesn't seem to be much need for that. This new parameter controls partition pruning for all queries: trivially, SELECT queries that affect partitioned tables are naturally under its control since they are using the new technology. However, while UPDATE/DELETE queries do not use the new code, we make the new GUC control their behavior also (stealing control from constraint_exclusion), because it is more natural, and it leads to a more natural transition to the future in which those queries will also use the new pruning code. Constraint exclusion still controls pruning for regular inheritance situations (those not involving partitioned tables).

Previously, you could partition by a boolean column as long as you spelled the bound values as string literals, for instance FOR VALUES IN ('t'). The trouble with this is that ruleutils.c printed that as FOR VALUES IN (TRUE), which is reasonable syntax but wasn't accepted by the grammar. That results in dump-and-reload failures for such cases. Apply a minimal fix that just causes TRUE and FALSE to be converted to strings 'true' and 'false'. This is pretty grotty, but it's too late for a more principled fix in v11 (to say nothing of v10). We should revisit the whole issue of how partition bound values are parsed for v12.

Instead of immediately constructing the string we need to emit into the .BKI file, preserve the items we extracted from the header file in a hash. This eases using the info for other purposes.

Also, commit 372728b0d introduced some other portability problems, as complained of by Stas Kelvich. We can improve matters by converting it to Perl. While we're at it, let's future-proof both this script and duplicate_oids to use Catalog.pm rather than having a bunch of ad-hoc logic for parsing catalog headers and .dat files. These scripts are thereby a bit slower, which doesn't seem like a problem for typical manual use. It is a little annoying for buildfarm purposes, but we should be able to fix that case by having genbki.pl make the check instead of parsing the headers twice. (That's not done in this commit, though.) Stas Kelvich, adjusted a bit by me Discussion: https://postgr.es/m/37D774E4-FE1F-437E-B3D2-593F314B7505@postgrespro.ru https://git.postgresql.org/pg/commitdiff/5602265f770f400a03b4a4ca22b3cd530c294bc2 - Fix duplicate_oids and unused_oids so user needn't cd to catalog dir. Previously, you had to cd into src/include/catalog before running either of these scripts. That's a bit tedious, so let's make the scripts do it for you. In passing, improve the initial comments in both scripts. Also remove unused_oids' code to complain about duplicate oids. That was added in yesterday's commit 5602265f7, but on second thought we shouldn't be randomly redefining the script's behavior that way. John Naylor and Tom Lane Discussion: https://postgr.es/m/37D774E4-FE1F-437E-B3D2-593F314B7505@postgrespro.ru https://git.postgresql.org/pg/commitdiff/dd4cc9d7069c04d0ee8ae040511274c6e71b60f7 - Avoid parsing catalog data twice during BKI file construction. In the wake of commit 5602265f7, we were doing duplicate-OID detection quite inefficiently, by invoking duplicate_oids which does all the same parsing of catalog headers and .dat files as genbki.pl does. That adds under half a second on modern machines, but quite a bit more on slow buildfarm critters, so it seems worth avoiding. Let's just extend genbki.pl a little so it can also detect duplicate OIDs, and remove the duplicate_oids call from the build process. (This also means that duplicate OID detection will happen during Windows builds, which AFAICS it didn't before.) This makes the use-case for duplicate_oids a bit dubious, but it's possible that people will still want to run that check without doing a whole build run, so let's keep that script. In passing, move down genbki.pl's creation of its temp output files so that it doesn't happen until after we've done parsing and validation of the input. This avoids leaving a lot of clutter around after a failure.

Add some debug printouts focused on the idea that MapViewOfFileEx might be rounding its virtual memory allocation up more than we expect (and, in particular, more than VirtualAllocEx does). Once we've seen what this reports in one of the failures on buildfarm members dory or jacana, we might revert this ... or perhaps just decrease the log level.

Don't put comments inside the macros, per complaint from Michael Paquier. Quote target directory path with single quotes, not double; that seems to be our project standard.

Apparently $(foreach ... $(call install_llvm_module,...)) doesn't work too well without a blank line ending the install_llvm_module macro.

I (tgl) originally coded the special case for pg_proc.pronargs as though it were a kind of default value. It seems better though to treat computable columns as an independent concern: this makes the code clearer, and probably a bit faster too since we needn't do work inside the per-column loop. Improve related comments, as well, in the expectation that there might be more cases like this in future. John Naylor, some additional comment-hacking by me Discussion: https://postgr.es/m/CAJVSVGW-D7OobzU=dybVT2JqZAx-4X1yvBJdavBmqQL05Q6CLw@mail.gmail.com https://git.postgresql.org/pg/commitdiff/45c6d75f8cd2399181063b4e0ec11c2664ebeda6 - Tweak reformat_dat_file.pl to make it more easily hand-invokable. Use the same code we already applied in duplicate_oids and unused_oids to let this script find Catalog.pm without help. This removes the need to supply a -I switch in most cases. Also, mark the script executable, again to follow the precedent of duplicate_oids and unused_oids. Now you can just do "./reformat_dat_file.pl pg_proc.dat" if you want to reformat only one or a few .dat files rather than all. It'd be possible to remove the -I switches in the Makefile's convenience targets, but I chose to leave them: they don't hurt anything, and it's possible that in weird VPATH situations they might be of value. https://git.postgresql.org/pg/commitdiff/84549ebd4c4d1941006056cfb2455a4983fb15a2 - Fix incorrect field type for PlannedStmt.jitFlags in outfuncs/readfuncs.

This change makes this module act more like most of our other low-level resource management modules. It's a caller error if something is not explicitly closed by the end of a successful transaction, so issue a WARNING about it. This would not actually have caught the file leak bug fixed in commit 231bcd080, because that was in a transaction-abort path; but it still seems like a good, and pretty cheap, cross-check.

The point of this is not really to remove redundancy in pg_language.dat; with only three entries, it's hardly worth it. Rather, it is to get to a point where there are exactly zero hard-coded numeric pg_proc OID references in the catalog .dat files. The lanvalidator column was the only remaining location of such references, and it seems like a good thing for future-proofing reasons to make it not be a special case. There are still a few places in the .dat files with numeric OID references to other catalogs, but after review I don't see any that seem worth changing at present. In each case there are just too few entries to make it worth the trouble to create lookup infrastructure. This doesn't change the emitted postgres.bki file, so no catversion bump. https://git.postgresql.org/pg/commitdiff/85475afdb6f4f630f2071235373a986e472a117b - Avoid wrong results for power() with NaN input on some platforms. Per spec, the result of power() should be NaN if either input is NaN. It appears that on some versions of Windows, the libc function does return NaN, but it also sets errno = EDOM, confusing our code that attempts to work around shortcomings of other platforms. Hence, add guard tests to avoid substituting a wrong result for the right one. It's been like this for a long time (and the odd behavior only appears in older MSVC releases, too) so back-patch to all supported branches.
