Look at the subdbid field in the first query result. You were logging
into the databsae with OID=66754 and the subscription "metro" belongs
to the database 14313. The second command doesn't show metro which is
not of the current database.

Thus you need to log in to the databse OID=14313 to manipulate on the
subsciption metro.
