Yes, recent versions of PostgreSQL support foreign keys and general
CHECK constraints as well.  You will probably run into some SQL
differences between Informix and Postgres but I don't think they are
major.

The PG documentation is online at www.postgresql.org, feel free to
check it out if you haven't already.
