Andres Freund 0fd38e1370 Don't skip SQL backends in logical decoding for visibility computation. ... The logical decoding patchset introduced PROC_IN_LOGICAL_DECODING flag PGXACT flag, that allows such backends to be skipped when computing the xmin horizon/snapshots. That's fine and sensible for walsenders streaming out logical changes, but not at all fine for SQL backends doing logical decoding. If the latter set that flag any change they have performed outside of logical decoding will not be regarded as visible - which e.g. can lead to that change being vacuumed away. Note that not setting the flag for SQL backends isn't particularly bothersome - the SQL backend doesn't do streaming, so it only runs for a limited amount of time. Per buildfarm member 'tick' and Alvaro. Backpatch to 9.4, where logical decoding was introduced.		11 years ago
