This seems pretty dubious to me, in particular that the identical -T
option will be passed willy-nilly into the pg_dump runs for every
database.  That seems more likely to be a foot-gun than something useful.

Also, if we believe that this has a safe use-case, why only -T, and
not pg_dump's other object selectivity options?
