Sure does, and it looks good.

But... will the resulting dump be consistent as far as foreign keys
are concerned? Or will the current -t warning still apply (YMMV as to
the consistency of the resulting dump)?

If it's my job to ensure foreign key consistency, an option that only
dumps foreign keys and/or omits the foreign keys from the dump would
also be essential... Grepping a full dump, as I said, is not nice,
plus the foreign keys are multi-line which complicates grepping.

If both table filtering and the foreign key options would be
implemented, one could truly do useful dumps using pg_dump alone. I
could dump only some tables sans the foreign keys, then dump the
foreign keys separately and take it from there.

I know that I can get the foreign keys from a schema-only dump. But an
"don't dump foreign keys" option would still help.
