There are a range of encryption functions available in contrib/pgcrypto 
in the source distribution.

Some encryption is one-way (so you can't recover the original password, 
just confirm a provided password matches it). Other encryption is 
two-way, but you usually have a separate key to encrypt the passwords then.
