Thanks Achilleas. I usually do the physical design in vi using sql
scripts, and I like to include a

why not bytea?
much more control, much more information, IMHO.
In our DB evolving from an initial 7.1 back in 2001, and currently on 9.0,
we have been storing everything binary in bytea's.
There are downsides in both solutions, you just have to have good reasons
to not use bytea.

Hi Achilleas,
Actually I was asking if bytea is the correct datatype, and if so, would
someone mind providing a simple example of how to insert and retrieve the
image through the psql

Most of the time people manipulate bytea's using a higher level programming

Thanks Karl, but I'm trying to do this from a psql shell. I can't use the C
functions there, can I?

Hi Misa,
That gives me a ERROR: must be superuser to use server-side lo_import()
on the client. I think this is enforced to preserve file permissions on the
server? I appreciate the suggestion, and I will keep it, but I think I
found a solution that meets my immediate need.
Thanks!

Thanks Misa, for confirming my suspicions about server permissions. Like I
said, what I came up will work for my simple needs. I have a script that
creates the table, inserts a test row, and successfully retrieves it, which
is all I need at this point.
I appreciate all the help from everyone.
