AFAIK, not easily. There was a post to the hackers list recently with
code for a "database connector" function. Using this it may be possible
to write your own referential integrity triggers that reference the other
database.. maybe not. I didn't look much into the code. There might be
something else around somewhere. Note that in order to enforce "full" RI
you will have to write these functions in both databases. Oh, and the
other database does have to be a Postgresql database with the above
mentioned code.
