WITH ENCRYPTION feature ?

[Robert Bernabe <rbernabe(at)sandmansystems(dot)com>]

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.  Many Thanks in advance for any 
clues.
