pg_shadow and pgcrypto

[Frank Cavaliero <fcavalie@xxxxxxxxxx>]

Hi all,

I'm currently performing a hash check
for password verification.    I'm generating an md5  hash
or checking for plain text in pg_shadow.  However, outside of these
two "out-of-the-box" options, what if someone is using pg-crypto
or any other PAM ?  How can I differentiate between say md5 and pgcrypto
?  I see the md5 is prefixed in hash in pg_shadow.  I was wondering
what other prefixes may exist, say for pgcrypto.  If you have an examples
of what a pgcrypto or any other PAM hash would look like (or what they
would at least begin with), that would be great.

Thanks,
Frank
