86232a49a43 Fix comment on gist_stratnum_btree
030e10ff1a3 Rename pg_constraint.conwithoutoverlaps to conperiod
a88c800deb6 Use daterange and YMD in without_overlaps tests instead of tsrange.
5577a71fb0c Use half-open interval notation in without_overlaps tests
34768ee3616 Add temporal FOREIGN KEY contraints
482e108cd38 Add test for REPLICA IDENTITY with a temporal key
