Support invalidating replication slots due to horizon and wal_level
Needed for logical decoding on a standby. Slots need to be invalidated because
of the horizon if rows required for logical decoding are removed. If the
primary's wal_level is lowered from 'logical', logical slots on the standby
need to be invalidated.
The new invalidation methods will be used in a subsequent commit.
Logical slots that have been invalidated can be identified via the new
pg_replication_slots.conflicting column.
See 6af1793954e for an overall design of logical decoding on a standby.
Bumps catversion for the addition of the new pg_replication_slots column.
