I've downloaded several versions of postgresql from several mirrors. On none of them did the md5 checksums from http://www.gtsm.com/postgres_sigs.html match the md5 checksum from the postgresql-*.tar.gz source file I downloaded.
As a follow-up to my last message, "md5sum --check" does work, you just need to use one that was built in the last couple of years.
