Subject: pgsql: Improve REPACK (CONCURRENTLY) error when wal_level < replica

Improve REPACK (CONCURRENTLY) error when wal_level < replica
The error emitted when REPACK (CONCURRENTLY) is run with too low a
wal_level is thrown by CheckSlotRequirements(), which is a bit
mysterious when the user doesn't know what's up. Add an upfront check
in check_concurrent_repack_requirements() for a more explicit, REPACK-
centered report, which is easier to understand -- this also saves
starting the worker just to have it die immediately.
