Hi, all, at
http://www.idyll.org/~t/www-tools/
you'll find an add-on function to PostgreSQL 6.5.3 that allows one to
do string searches through large objects.
It's not a terribly good hack, but it works ;).
I do plan on extending this add-on to support regular expressions Real
Soon.
There are a couple of other software hacks on the same page, including
one that lets you retrieve large objects through the AOLserver database
driver for PostgreSQL.
cheers,
