You mean like this: 
http://keys.fedoraproject.org/pks/lookup?search=0x442df0f8&op=vindex

Still

plain HTTP there (on a somewhat unrelated site), also:
* short key ID (no fingerprint) listed on http://yum.postgresql.org
* DSA-1 key: 3 don'ts in a row.

The situation is a bit better for the APT repository:
http://wiki.postgresql.org/wiki/Apt

* 4096-bit RSA key
* instructs to download key from same site - using plain http
  (but HTTPS is available - GoDaddy CA domain control validated)
* (short key ID used in documentation only)

In contrary to the Yum repository signing key this OpenPGP key is
signed by someone else, notably a Debian developer, so verifying it
via the web of trust / strong set /may/ succeed.

Maybe a new policy document would solve it...
http://wiki.postgresql.org/wiki/Policies
http://wiki.postgresql.org/wiki/ReleasePrep

This said, I'm glad that the Postgresql Global Development Group do
provide us with these repositories.
