Don't show tables redundantly when their schema is published.

Don't show tables redundantly when their schema is published.

A table published both explicitly and through its schema (FOR TABLES IN
SCHEMA) was listed twice by \dRp+ and \d.  Since publishing a schema
publishes its tables in full, the explicit entry's row filter has no
effect; suppress it when the same publication also publishes the table's
schema.
