Hi
Currently pg_create_physical_replication_slot() may refer to
the deprecated wal_level setting "archive":
postgres=# SHOW wal_level ;
wal_level
-----------
minimal
(1 row)
postgres=# SELECT pg_create_physical_replication_slot('some_slot');
ERROR: replication slots can only be used if wal_level is >= archive
Patch changes the error message to:
ERROR: replication slots can only be used if wal_level is "replica" or "logical"
Explicitly naming the valid WAL levels matches the wording in the wal_level
error hint used in a couple of places, i.e.
"wal_level must be set to "replica" or "logical" at server start."
