From: pinker <pinker@xxxxxxx> > it's a cloud and no plpythonu extension avaiable unfortunately You're misunderstanding him. See David's post for an example, but the point was that you can control all of this from an *external* Perl, Python, Bash, whatever program on the command line at the shell. In pseudo-code, probably fed by a "find" command piping filenames to it: while more files do { read in a file name & add to list } while (list.length < 1000); process entire list with \copy commands to 1 psql command I've left all kinds of checks out of that, but that's the basic thing that you need, implement in whatever scripting language you're comfortable with.
