Re: [Fwd: Help with Conversion] - Mailing list pgsql-general

Hi,

You could look at or2pg script provided in postgresql sources, contrib section.
It might do the trick for you.

I would request you to join postgresql-general mailing list at
http://www.postgresql.org/lists.html. You could get further help you need in
your migration.

Regards
  Shridhar
