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?
