Amit Kapila	581092c907	Stabilize the test added by commit 022564f60c. ... The test was unstable in branches 14 and 15 as we were relying on the number of changes in the table having a toast column to start streaming. On branches >= 16, we have a GUC debug_logical_replication_streaming which can stream each change, so the test was stable in those branches. Change the test to use PREPARE TRANSACTION as that should make the result consistent and test the code changed in 022564f60c.

Amit Kapila	19890a064e	Add option to enable two_phase commits via pg_create_logical_replication_slot. ... Commit 0aa8a01d04 extends the output plugin API to allow decoding of prepared xacts and allowed the user to enable/disable the two-phase option via pg_logical_slot_get_changes(). This can lead to a problem such that the first time when it gets changes via pg_logical_slot_get_changes() without two_phase option enabled it will not get the prepared even though prepare is after consistent snapshot. Now next time during getting changes, if the two_phase option is enabled it can skip prepare because by that time start decoding point has been moved. So the user will only get commit prepared. Allow to enable/disable this option at the create slot time and default will be false. It will break the existing slots which is fine in a major release.

Noah Misch	388b959315	Raise a timeout to 180s, in contrib/test_decoding. ... Per buildfarm member hornet. The test is new in v14, so no back-patch.	5 years ago
Amit Kapila	a271a1b50e	Allow decoding at prepare time in ReorderBuffer. ... This patch allows PREPARE-time decoding of two-phase transactions (if the output plugin supports this capability), in which case the transactions are replayed at PREPARE and then committed later when COMMIT PREPARED arrives. Now that we decode the changes before the commit, the concurrent aborts may cause failures when the output plugin consults catalogs (both system and user-defined). We detect such failures with a special sqlerrcode ERRCODE_TRANSACTION_ROLLBACK introduced by commit 7259736a6e and stop decoding the remaining changes. Then we rollback the changes when rollback prepared is encountered.
