... and your question is what, exactly?

For crypto options, see
http://www.ca.postgresql.org/docs/faq-english.html#4.28 -- I'd think
pgcrypto is probably the best bet for you.

When a PL/PgSQL function is defined, some minimal parsing is done. The
first time in a given session that it is called, it is planned (once),
and the plan is used for future executions of the function (within that
session).

I want to encrypt certain data fields in  some tables in order to keep a
customer happy about security, ( and since this is on a hosted site, I
can't control security anyway )

How fast are pl/pgsql functions? Can pl/pgsql functions be pre compiled
except for the arguments?

If anyone is using encrypted data in their database, and has experience, I would love to talk 
with them by phone or email, in particular, about escaping the data after it comes out of the 
'encrypt()' function
