plperl or C or custom guc .. the using plperl is probably most simple and fast

I don't know what do you do - but some times better is don't use a
session variables on server - just use a application variables
together with stored procedures. What I remember my last bigger
project, we did a some problems with session variables from PHP, where
PHP sessions sometimes recycled a db session, so probably better to
don't use it.
