There are three main changes here: 1. No longer cause a start failure in a standby if the feature is disabled in postgresql.conf but enabled in the master. This reverts one part of commit 4f3924d9cd43; what we keep is the ability of the standby to activate/deactivate the module (which includes creating and removing segments as appropriate) during replay of such actions in the master. 2. Replay WAL records affecting commitTS even if the feature is disabled. This means the standby will always have the same state as the master after replay. 3. Have COMMIT PREPARE record the transaction commit time as well. We were previously only applying it in the normal transaction commit path.

Backpatch to 9.5, where this code was introduced. Per bug reports from Fujii Masao and subsequent discussion. |
