hi. some trivial issue:
in src/backend/catalog/index.c
/* * System attributes are never null, so no need to check. */
if (attnum <= 0)
since you already checked attnum == 0
so here you can just attnum < 0?
-------------------------------------------------
ERROR: column "valid_at" named in WITHOUT OVERLAPS is not a range type
IMHO, "named" is unnecessary.
-------------------------------------------------
doc/src/sgml/catalogs.sgml
pg_constraint adds another attribute (column): contemporal, seems no doc entry.
also the temporal in oxford definition is "relating to time", here we
can deal with range.
So maybe "temporal" is not that accurate?
