Thread: pgsql: Fast default trigger and expand_tuple fixes
Fast default trigger and expand_tuple fixes Ensure that triggers get properly filled in tuples for the OLD value. Also fix the logic of detecting missing null values. The previous logic failed to detect a missing null column before the first missing column with a default. Fixing this has simplified the logic a bit. Regression tests are added to test changes. This should ensure better coverage of expand_tuple(). Original bug reports, and some code and test scripts from Tomas Vondra Backpatch to release 11.
