pgsql: Improve pg_restore's -t switch to match all types of relations.

Improve pg_restore's -t switch to match all types of relations.

-t will now match views, foreign tables, materialized views, and sequences,
not only plain tables. This is more useful, and also more consistent with
the behavior of pg_dump's -t switch, which has always matched all relation
types.

We're still not there on matching pg_dump's behavior entirely, so mention
that in the docs.
