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.
