If you check CVS you'll see that today the SGML documentation for CREATE TABLE has been updated to reflect version 7's support for foreign keys. So, the next beta or first release candidate should have it documented...

I am using version 7.0 beta 5... and btw, I found a little snippit of code syntax on this page: http://www.postgresql.org/projects/devel-refint.html which is good enough to meet my needs for now. hasta, Andy
Better try to install PostgreSQL version 7 and experiment on referential
integrity...

Final will have the appropriate doc changes. Sorry for the delay, I just forgot a doc patch in my mailbox.

AFAIK (and I led the project),
v7.0 (released soon and the version he asked about) has a
fear amount of FK support. The implementation misses only
MATCH PARTIAL and PENDANT from the SQL3 specs, so it's far
more than SQL92!
Special thanks go to Stephan Szabo and Don Baccus; both where
major contributors to the project.
