Thread: pgsql: Optionally don't error out due to preexisting slots in commandli
Optionally don't error out due to preexisting slots in commandline utilities. pg_receivexlog and pg_recvlogical error out when --create-slot is specified and a slot with the same name already exists. In some cases, especially with pg_receivexlog, that's rather annoying and requires additional scripting. Backpatch to 9.5 as slot control functions have newly been added to pg_receivexlog, and there doesn't seem much point leaving it in a less useful state.

Andres, Coverity is pointing out that this commit missed the shot when sqlstate is NULL in CreateReplicationSlot and this would crash. Something like the patch attached look adapted to me, vacuumdb.c doing the necessary checks similarly. Regards, -- Michael
