Re: can a linux program, running on the client side, generate data to load a temp table ?

Ya, I've used \copy for copying data in the past. But if I'm not mistaken,
the "\copy... from program" runs on the server side. If I'm wrong about
that, if there's a client side version of this, I'm all ears ! And FWIW, a
future release that has this would be great !

plperlu might work in this case. I need the "untrusted" version because I
need to dump a bytea blob out to a file, unzip it, query it (it's a SQLite
DB), use the results of the query to load a temp table. So I need to make
system calls that write to disk and run external programs. I work in a
large corp and made the request to get that up on a DB instance.
Thankfully, I already have a superuser role that might be allowed to
execute the plperlu script.
