For example:Table A-id (PK)-name Table B-table_a_id (PK, FK)-address When I do an insert on table B, the database check if value for column “table_a_id” exists in table ABut, if I do an update of column “address” of table B, does the database check again? My question is due to the nature of and update in postgres, that basically is a new version “insert”.
