Log Message: ----------- Fix incorrect logic in plpgsql for cleanup after evaluation of non-simple expressions. We need to deal with this when handling subscripts in an array assignment, and also when catching an exception. In an Assert-enabled build these omissions led to Assert failures, but I think in a normal build the only consequence would be short-term memory leakage; which may explain why this wasn't reported from the field long ago. Back-patch to all supported versions. 7.4 doesn't have exceptions, but otherwise these bugs go all the way back.
