I have two databases that are clustered. One is my primary (DB1) and the
other is my secondary (DB2). Both have the same tables and schemas. Could I
use pg_repack against each of these separately (I am wanting to do this at a
"by table" level) to clean up dead space that hasn't been returned? Should I
be doing it this way? I would assume that dead space in DB1 would also exist
in DB2 as deletes are performed as part of the replication process, but the
reclamation of space back to the system wouldn't take place? Just curious if
the fact that the database is being replicated would prevent the needed
steps from occurring as it's my understanding that you can't drop a table
that's being replicated between two instances.
