I'm not exactly positive, but I believe pg_extractor has an exclude type option that might fit your requirement. You can download it here:
https://github.com/omniti-labs/pg_extractor Also note that this is a Python program, so you might even be able to hack some change into it to do what you need. Good luck, and may the bytes be with you. On Sat, May 2, 2015 at 10:27 AM, Alanoly Andrews <alano...@invera.com> wrote: > Thanks Vincent.
