If you had read the pg_dump manpage, you would have seen:

  -s, --schema-only        dump only the schema, no data

The schema dump will be close to ANSI-compatible, but you will
probably have to edit it a bit.

I did read the page.  Been there done that, ran the script.  My question was if there was a canned script out there that I didn't have to clean up on the fly.  This will be an cron job for a convoluted development process.  Thanks though.

Yeah, that would be a bit trickier than a one-off edit.  :)

If your schema isn't using any non-standard features, I would think that
the result of pg_dump would be pretty standard, with the exception of a
few SET commands at the front and the ALTER OWNER commands.  (The latter
can be suppressed with --no-owner.)  What exactly is giving you a
problem?

No problems.  I am about to write a python script to cleanup the output of pg_dump.  Before I do I just wanted to verify that there wasn't an already available script which I could feed  directly into another ansi compliant database without modification.  No sense reinventing the wheel.  The output of pg_dump is pretty clean for this purpose already. just thought I'd ask beforehand.
