No, there are no formalized tests at all that exercise pg_dump.

The informal test that's been around for a while is to pg_dump
the regression database, load into a fresh DB, pg_dump again,
and compare the second dump's output to the first's. But there's
no automation for this, and I'm not sure you can really expect
the resulting scripts to be bit-for-bit the same anyway (there
might be ordering differences).

If you feel like developing a more believable testing strategy
for pg_dump, ain't nobody gonna get in your way.
