Is there any built in function in PGSQL to Encrypt/Decrypt a text before
storing in field? If yes, which algorithms it supports and what is the
maximum key size?

Take a look at contrib/pgcrypto. It supports a wide range of different
algorithms and key sizes. There's a README file
Quick question: I have installed PG 8.2.x on a customer's system and we will be
storing a lot of critical data on it. It needs to be backed up maybe twice a
day. It's very easy to back data up with the pgadmin tool (great tool btw) but
we need an automated solution that we can configure.

I believe it's because the result of date_trunc depends on the time
