pgsql: Allow pg_dump to include/exclude child tables automatically.

Allow pg_dump to include/exclude child tables automatically.

This patch adds new pg_dump switches
--table-and-children=pattern
--exclude-table-and-children=pattern
--exclude-table-data-and-children=pattern
which act the same as the existing --table, --exclude-table, and
--exclude-table-data switches, except that any partitions or
inheritance child tables of the table(s) matching the pattern
are also included or excluded.
