Yeah, that's what I do as well. With just a little bit of work you can make this sort of thing really easy to do. The trick is to create a script (I generally use Python as well, but Perl is good too) that reads from stdin and writes to stdout and that looks like what pg_dump spits out (which is very trivial). That way you can use it like this: cat my_file | custom_filter | psql -e my_database making it easy to automate. Jason --- Andrew Gould <andrewgould@yahoo.com> wrote: > I think that is correct.
