Subject: [PATCH v4 2/4] Add a test case to cover pg_dump with --compress=none.

This brings the coverage of compress_none.c up from about 64%
to 90%, in particular covering the new code added in the previous
patch.

This adds perhaps 2% to the runtime of 002_pg_dump.pl.  It could
be argued that compress_none.c is simple enough to not require
permanent memorialization in a test case; but it's less simple
than it was before, so maybe we want this.
