No, unfortunately postgresql does not support assertions.
If I understand the idea correctly, when such an assertion is in effect, entries into the super-table and sub-table can be made only inside a transaction - otherwise, an attempt to insert a row into the main table will violate the assertion.
Am I correct? Received on Wed Sep 08 2004 - 01:57:10 CDT
