We were not updating the partition map cache in the subscriber even when the corresponding remote rel is changed. Due to this data was getting incorrectly replicated for partition tables after the publisher has changed the table schema. Fix it by resetting the required entries in the partition map cache after receiving a new relation mapping from the publisher.

In logical replication, we will check if the target table on the subscriber is updatable by comparing the replica identity of the table on the publisher with the table on the subscriber. When the target table is a partitioned table, we only check its replica identity but not for the partition tables. This leads to assertion failure while applying changes for update/delete as we expect those to succeed only when the corresponding partition table has a primary key or has a replica identity defined. Fix it by checking the replica identity of the partition table while applying changes.

We build the partition map entries on subscribers while applying the changes for update/delete on partitions. The component relation in each entry is closed after its use so we need to update it on successive use of cache entries. This problem was there since the original commit f1ac27b that introduced this code but we didn't notice it till the recent commit 26b3455 started to use the component relation of partition map cache entry.

Ok, I got that 604651880c7 was already take in-tree, so only affecting pieces are (removal of) |
SPI_commit previously left it up to the caller to recover from any error occurring during commit. Since that's complicated and requires use of low-level xact.c facilities, it's not too surprising that no caller got it right. Let's move the responsibility for cleanup into spi.c. Doing that requires redefining SPI_commit as starting a new transaction, so that it becomes equivalent to SPI_commit_and_chain except that you get default transaction characteristics instead of preserving the prior transaction's characteristics. We can make this pretty transparent API-wise by redefining SPI_start_transaction() as a no-op. Callers that expect to do something in between might be surprised, but available evidence is that no callers do so. Having made that API redefinition, we can fix this mess by having SPI_commit[_and_chain] trap errors and start a new, clean transaction before re-throwing the error. Likewise for SPI_rollback[_and_chain]. Some cleanup is also needed in AtEOXact_SPI, which was nowhere near smart enough to deal with SPI contexts nested inside a committing context. While plperl and pltcl need no changes beyond removing their now-useless SPI_start_transaction() calls, plpython needs some more work because it hadn't gotten the memo about catching commit/rollback errors in the first place. Such an error resulted in longjmp'ing out of the Python interpreter, which leaks Python stack entries at present and is reported to crash Python 3.11 altogether. Add the missing logic to catch such errors and convert them into Python exceptions. This is a back-patch of commit 2e51781. That's now aged long enough to reduce the concerns about whether it will break something, and we do need to ensure that supported branches will work with Python 3.11.

postgres/postgres@3238b5c330bc vs 16df3d57c330 some free/pfree patterns was applied improperly, fixed. |
When rebuilding the relation mapping on subscribers, we were not releasing the attribute mapping's memory which was no longer required. The attribute mapping used in logical tuple conversion was refactored in PG13 (by commit e1551f9) but we forgot to update the related code that frees the attribute map.

Remove the need to edit back-branch-specific code sites when back-patching the addition of a PostgreSQL::Test::Utils symbol. Replace per-symbol, incomplete alias lists. Give old and new package names the same EXPORT and EXPORT_OK semantics. Back-patch to v10 (all supported versions). Reviewed by Andrew Dunstan.

I'll await for review from at least one of requested reviewers here. Also I'll await for cloudbery-dev list discussion to agree on something |
