Most important thing: upgrade this version of PostgreSQL. You can't even
get 7.3 from the main site any more, so you'll have to look on
ftp://ftp-archives.postgresql.org/
The last release was 7.3.21 - work through the release notes and then
download as soon as possible.

Well, you don't want to be making any changes to a PostgreSQL version
that old - it will be impossible to find anyone to help with it. I'd
suggest encrypting a filesystem and putting your database on that. That
will impact performance of course.
If you only want to encrypt a few tables, you could look at splitting
where the files are stored. That might involve setting up symlinks, I
can't remember if 7.3 supported tablespaces.
If you do put some files on the encrypted filesystem and some on the
unencrypted one make sure you don't start PG until both are available. I
don't know what would happen if one wasn't but it's unlikely to be fun.
