[PATCH] add option to pg_dumpall to exclude tables from the dump

A new option -T --exlude-table for pg_dumpall. This option is then
passed through to the pg_dump which really does the work.
This feature can be used to exclude large tables that are known not
to change from a database backup dump so that only the changing parts
of the database are dumped.
