Hi Folks,

Here is an updated patchset from Georgios, with minor assistance from myself.
The comments above should be addressed, but please let us know if
there are other things to go over. A functional change in this
patchset is when `--compress=none` is passed to pg_dump, it will not
compress for directory type (previously, it would use gzip if
present). The previous default behavior is retained.
