WITH ENCRYPTION

Hi,
    Is there a translation of this MSSQL feature in PostgreSQL? It's
still actually possible to decrypt the encrypted stored procedure in the
server but end of the day it should be recognized that all these efforts
will just serve to make things slightly more difficult (e.g. leaving
your car unlocked instead of locked or leaving the keys inside). Anyways
the feature in MSSQL will encrypt the stored procedure in the server
such that when it's viewed by a sysad or anybody else, they will
encrypted text instead of T-SQL code.  Thanks in advance.
