* Reformat some node commentsPeter Eisentraut9 days
| | | | | | | | | | | Use per-field comments for IndexInfo, instead of one big header comment listing all the fields. This makes the relevant comments easier to find, and it will also make it less likely that comments are not updated when fields are added or removed, as has happened in the past.

* Fix missing FSM vacuum opportunities on tables without indexes.Masahiko Sawada9 days
| | | | | | | | | | | | | | | | | | | | | | Commit c120550edb86 optimized the vacuuming of relations without indexes (a.k.a. one-pass strategy) by directly marking dead item IDs as LP_UNUSED. However, the periodic FSM vacuum was still checking if dead item IDs had been marked as LP_DEAD when attempting to vacuum the FSM every VACUUM_FSM_EVERY_PAGES blocks. This condition was never met due to the optimization, resulting in missed FSM vacuum opportunities. This commit modifies the periodic FSM vacuum condition to use the number of tuples deleted during HOT pruning. This count includes items marked as either LP_UNUSED or LP_REDIRECT, both of which are expected to result in new free space to report. Back-patch to v17 where the vacuum optimization for tables with no indexes was introduced.

* Fix bug in archive streamer with LZ4 decompressionMichael Paquier9 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When decompressing some input data, the calculation for the initial starting point and the initial size were incorrect, potentially leading to failures when decompressing contents with LZ4. These initialization points are fixed in this commit, bringing the logic closer to what exists for gzip and zstd. The contents of the compressed data is clear (for example backups taken with LZ4 can still be decompressed with a "lz4" command), only the decompression part reading the input data was impacted by this issue. This code path impacts pg_basebackup and pg_verifybackup, which can use the LZ4 decompression routines with an archive streamer, or any tools that try to use the archive streamers in src/fe_utils/. The issue is easier to reproduce with files that have a low-compression rate, like ones filled with random data, for a size of at least 512kB, but this could happen with anything as long as it is stored in a data folder. Some tests are added based on this idea, with a file filled with random bytes grabbed from the backend, written at the root of the data folder. This is proving good enough to reproduce the original problem.

* Move code for the bytea data type from varlena.c to new bytea.cMichael Paquier9 days
| | | | | | | | | | | | | | | | | | | | This commit moves all the routines related to the bytea data type into its own new file, called bytea.c, clearing some of the bloat in varlena.c. This includes the routines for: - Input, output, receive and send - Comparison - Casts to integer types - bytea-specific functions The internals of the routines moved here are unchanged, with one exception. This comes with a twist in bytea_string_agg_transfn(), where the call to makeStringAggState() is replaced by the internals of this routine, still located in varlena.c. This simplifies the move to the new file by not having to expose makeStringAggState().

* Show sizes of FETCH queries as constants in pg_stat_statementsMichael Paquier9 days
| | | | | | | | | | | | | | | | | | | | | | | | | | Prior to this patch, every FETCH call would generate a unique queryId with a different size specified. Depending on the workloads, this could lead to a significant bloat in pg_stat_statements, as repeatedly calling a specific cursor would result in a new queryId each time. For example, FETCH 1 c1; and FETCH 2 c1; would produce different queryIds. This patch improves the situation by normalizing the fetch size, so as semantically similar statements generate the same queryId. As a result, statements like the below, which differ syntactically but have the same effect, will now share a single queryId: FETCH FROM c1 FETCH NEXT c1 FETCH 1 c1 In order to do a normalization based on the keyword used in FETCH, FetchStmt is tweaked with a new FetchDirectionKeywords. This matters for "howMany", which could be set to a negative value depending on the direction, and we want to normalize the queries with enough information about the direction keywords provided, including RELATIVE, ABSOLUTE or all the ALL variants.

* Silence valgrind about pg_numa_touch_mem_if_requiredTomas Vondra10 days
| | | | | | | | | | | | | | | | | | | | | | | When querying NUMA status of pages in shared memory, we need to touch the memory first to get valid results. This may trigger valgrind reports, because some of the memory (e.g. unpinned buffers) may be marked as noaccess. Solved by adding a valgrind suppresion. An alternative would be to adjust the access/noaccess status before touching the memory, but that seems far too invasive. It would require all those places to have detailed knowledge of what the shared memory stores. The pg_numa_touch_mem_if_required() macro is replaced with a function. Macros are invisible to suppressions, so it'd have to suppress reports for the caller - e.g. pg_get_shmem_allocations_numa(). So we'd suppress reports for the whole function, and that seems to heavy-handed. It might easily hide other valid issues.

* Limit the size of numa_move_pages requestsTomas Vondra10 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's a kernel bug in do_pages_stat(), affecting systems combining 64-bit kernel and 32-bit user space. The function splits the request into chunks of 16 pointers, but forgets the pointers are 32-bit when advancing to the next chunk. Some of the pointers get skipped, and memory after the array is interpreted as pointers. The result is that the produced status of memory pages is mostly bogus. Systems combining 64-bit and 32-bit environments like this might seem rare, but that's not the case - all 32-bit Debian packages are built in a 32-bit chroot on a system with a 64-bit kernel. This is a long-standing kernel bug (since 2010), affecting pretty much all kernels, so it'll take time until all systems get a fixed kernel. Luckily, we can work around the issue by chunking the requests the same way do_pages_stat() does, at least on affected systems. We don't know what kernel a 32-bit build will run on, so all 32-bit builds use chunks of 16 elements (the largest chunk before hitting the issue). 64-bit builds are not affected by this issue, and so could work without the chunking. But chunking has other advantages, so we apply chunking even for 64-bit builds, with chunks of 1024 elements.

* Improve error handling of libxml2 calls in xml.cMichael Paquier10 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | This commit fixes some defects in the backend's xml.c, found upon inspection of the internals of libxml2: - xmlEncodeSpecialChars() can fail on malloc(), returning NULL back to the caller. xmltext() assumed that this could never happen. Like other code paths, a TRY/CATCH block is added there, covering also the fact that cstring_to_text_with_len() could fail a memory allocation, where the backend would miss to free the buffer allocated by xmlEncodeSpecialChars(). - Some libxml2 routines called in xmlelement() can return NULL, like xmlAddChildList() or xmlTextWriterStartElement(). Dedicated errors are added for them. - xml_xmlnodetoxmltype() missed that xmlXPathCastNodeToString() can fail on an allocation failure. In this case, the call can just be moved to the existing TRY/CATCH block. All these code paths would cause the server to crash. As this is unlikely a problem in practice, no backpatch is done. Jim and I have caught these defects, not sure who has scored the most. The contrib module xml2/ has similar defects, which will be addressed in a separate change.

* Fix some new issues with planning of PlaceHolderVars.Tom Lane12 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the wake of commit a16ef313f, we need to deal with more cases involving PlaceHolderVars in NestLoopParams than we did before. For one thing, a16ef313f was incorrect to suppose that we could rely on the required-outer relids of the lefthand path to decide placement of nestloop-parameter PHVs. As Richard Guo argued at the time, we must look at the required-outer relids of the join path itself. For another, we have to apply replace_nestloop_params() to such a PHV's expression, in case it contains references to values that will be supplied from NestLoopParams of higher-level nestloops. For another, we need to be more careful about the phnullingrels of the PHV than we were being. identify_current_nestloop_params only bothered to ensure that the phnullingrels didn't contain "too many" relids, but now it has to be exact, because setrefs.c will apply both NRM_SUBSET and NRM_SUPERSET checks in different places. We can compute the correct relids by determining the set of outer joins that should be able to null the PHV and then subtracting whatever's been applied at or below this join. Do the same for plain Vars, too. (This should make it possible to use NRM_EQUAL to process nestloop params in setrefs.c, but I won't risk making such a change in v18 now.) Lastly, if a nestloop parameter PHV was pulled up out of a subquery and it contains a subquery that was originally pushed down from this query level, then that will still be represented as a SubLink, because SS_process_sublinks won't recurse into outer PHVs, so it didn't get transformed during expression preprocessing in the subquery. We can substitute the version of the PHV's expression appearing in its PlaceHolderInfo to ensure that that preprocessing has happened. (Seems like this processing sequence could stand to be redesigned, but again, late in v18 development is not the time for that.) It's not very clear to me why the old have_dangerous_phv join-order restriction prevented us from seeing the last three of these problems. But given the lack of field complaints, it must have done so.

* Obtain required table lock during cross-table constraint updates.Tom Lane12 days
| | | | | | | | | | | | | | | | | | | | | | | | | Sometimes a table's constraint may depend on a column of another table, so that we have to update the constraint when changing the referenced column's type. We need to have lock on the constraint's table to do that. ATPostAlterTypeCleanup believed that this case was only possible for FOREIGN KEY constraints, but it's wrong at least for CHECK and EXCLUDE constraints; and in general, we'd probably need exclusive lock to alter any sort of constraint. So just remove the contype check and acquire lock for any other table. This prevents a "you don't have lock" assertion failure, though no ill effect is observed in production builds. We'll error out later anyway because we don't presently support physically altering column types within stored composite columns. But the catalog-munging is basically all there, so we may as well make that part work.

* pg_recvlogical: Rename --two-phase and --failover options.Peter Eisentraut12 days
| | | | | | | | | | | | | | | | | | | This commit renames the pg_recvlogical options --two-phase and --failover to --enable-two-phase and --enable-failover, respectively. The new names distinguish these enabling options from action options like --start and --create-slot, while clearly indicating their purpose to enable specific logical slot features. The option --failover is new in PostgreSQL 18 (commit cf2655a9029), so no compatibility break there. The option --two-phase has existed since PostgreSQL 15 (commit cda03cfed6b), so for compatibility we keep the old option name --two-phase around as deprecated. Also note that pg_createsubscriber has acquired an --enable-two-phase option, so this increases consistency across tools.

* Fix CheckPointReplicationSlots() with max_replication_slots == 0Alexander Korotkov14 days
| | | | | | | | | | | | | | | | ca307d5cec90 made CheckPointReplicationSlots() unconditionally call ReplicationSlotsComputeRequiredLSN(). It causes an assertion trap when max_replication_slots equals 0. This commit makes CheckPointReplicationSlots() call ReplicationSlotsComputeRequiredLSN() only when at least one slot gets its last_saved_restart_lsn updated. That avoids an assert trap and also saves some cycles when no one slot has last_saved_restart_lsn updated. Based on ideas from Dilip Kumar <dilipbalaut@gmail.com> and Hayato Kuroda <kuroda.hayato@fujitsu.com>.
