Обсуждение: pgsql: Prevent intratransaction memory leak when a subtransaction is

Log Message:
-----------
Prevent intratransaction memory leak when a subtransaction is aborted
in the middle of executing a SPI query.  This doesn't entirely fix the
problem of memory leakage in plpgsql exception handling, but it should
get rid of the lion's share of leakage.
