Hello Thanks, I missed this thread.
> + <term><literal>CHECKPOINT { 'fast' | 'spread' > }</replaceable></literal></term> Unpaired </replaceable> tag in docs. That was all I noticed in 0001. Still not sure where is the difference between "change NOWAIT to WAIT" and "change NOWAIT to something else descriptive". But fine, I can live with WAIT. (one note: the exact command is visible to the user when log_replication_commands is enabled, not completely hidden) 0002 breaks "create subscription (with create_slot true)" when the publish server is an earlier version: postgres=# create subscription test CONNECTION 'host=127.0.0.1 user=postgres' PUBLICATION test with (create_slot = true); ERROR: could not create replication slot "test": ERROR: syntax error regards, Sergei
