Yes.
It declares sl_table and sl_sequence and sl_set as catalog.
It does a
SELECT ...... from @NAMESPACE@.sl_table T, @NAMESPACE@.sl_set S, "pg_catalog".pg_class PGC,
"pg_catalog".pg_namespacePGN, "pg_catalog".pg_index PGX, "pg_catalog".pg_class PGXC
where ... for update
in the code being executed by the 'set add table'.
(We also do select for update commands in many other places during
cluster configuration commands)
