Reserve replication slots specifically for REPACK Add a new GUC max_repack_replication_slots, which lets the user reserve some additional replication slots for concurrent repack (and only concurrent repack). With this, the user doesn't have to worry about changing the max_replication_slots in order to cater for use of concurrent repack.
(We still use the same pool of bgworkers though, but that's less commonly a problem than slots.)
