not directly, no. at least not yet :) 6.6 is rumoured to have full
support.
for now you can use refint ( $PGSQL_SRC_ROOT/contrib/spi/refint.* ), which
handles referential integrity. check_primary_key() and
check_foreign_key() are the two functions involved. youd also need two
triggers, one per table.
i could've sworn this got added to the FAQ...
