It seems to be running much faster (probably after removing the
randomization), and apparently it passed the create_view tests without
crashing, but then crashed at 'constraints' (again, because of OOM).
PortalMemory: 8192 total in 1 blocks; 7880 free (0 chunks); 312 used
PortalHeapMemory: 1024 total in 1 blocks; 840 free (0 chunks); 184 used
ExecutorState: 769654952 total in 103 blocks; 114984 free (296
chunks); 769539968 used
ExprContext: 0 total in 0 blocks; 0 free (0 chunks); 0 used
I suppose we don't expect 760MB ExecutorState here. Also, there's ~60MB
MessageContext.
It's still running, so I'm attaching the relevant part of log (again,
with MemoryContextStats for backends with VSS >= 512MB .
FWIW, it's running against a844c29966d7c0cd6a457e9324f175349bb12df0.
