Peter Eisentraut 89f908a6d0 Add temporal FOREIGN KEY contraints ... Add PERIOD clause to foreign key constraint definitions. This is supported for range and multirange types. Temporal foreign keys check for range containment instead of equality. This feature matches the behavior of the SQL standard temporal foreign keys, but it works on PostgreSQL's native ranges instead of SQL's "periods", which don't exist in PostgreSQL (yet). Reference actions ON {UPDATE,DELETE} {CASCADE,SET NULL,SET DEFAULT} are not supported yet. (previously committed as 34768ee361, reverted by 8aee330af55; this is essentially unchanged from those) Author: Paul A.
