Peter Eisentraut 46a0cd4cef Add temporal PRIMARY KEY and UNIQUE constraints 
Add WITHOUT OVERLAPS clause to PRIMARY KEY and UNIQUE constraints.
These are backed by GiST indexes instead of B-tree indexes, since they
are essentially exclusion constraints with = for the scalar parts of
the key and && for the temporal part.
