test_pg_dump TAP test whitespace cleanup
test_pg_dump TAP test whitespace cleanup

The formatting of the perl hashes used in the TAP tests for test_pg_dump
was rather horribly inconsistent and made it more difficult than it
really should have been to add new tests or adjust what tests are for
what runs, etc.

Reformat to clean that all up.

Whitespace-only changes.
