Hi,
it seems e94568ecc10 has a pretty bad memory leak. A simple
pgbench -i -s 300
allocates ~32GB of memory before it fails
vacuum...
set primary keys...
ERROR: out of memory
DETAIL: Failed on request of size 134184960.
The relevant bit from the memory context stats:
TupleSort main: 33278738504 total in 263 blocks; 78848 free (23 chunks);
33278659656 used
regards
