we have a daily vacuumdb and analyze job, generally speaking it's done in seconds, sometimes it suddenly running more than tens of minutes with same bind variable values and huge temp space got used and at that time, explain show "Hash Anti join, Hash Right join" with seq scan two tables.

Hi James,
I think it'd be much easier to help you with investigating this issue if
you shared the actual queries, and the full EXPLAIN ANALYZE output both
with and without disabled hashjoin. Or even better, share a script that
reproduces the issue (creates tables, loads data, runs the queries).
BTW you suggested each partition has ~250k rows, but the explain plan
snippet you shared does not seem to be consistent with that - it only
shows 2500-5000 rows per partition. If you run ANALYZE on the table,
does that change the plan?

generally speaking, it run in less than 2 seconds, but sometimes, it suddenly go to bad plan.
schema:
all three tables are hash partitioned tables(partitionkeyid column is the top index key too), generally speaking with index scan and partition prunning
with partitionkeyid, it's good plan. but sometimes, optimizer suddenly go to "Hash Right Join" and seq scan on that large table "testaa.wmpct, that made very
bad plan. from the cost, looks like optimizer try to calculate cost for all partitions bitmapindex scan that show huge cost but actually only a small part of
partition needed other (never executed). and similar to estimate the "rows" for leftoutjoin, that made huge difference too.
no idea how to make optimizer to consider partition prunning for this SQL case ?
--the bad plan explain output, with analyze mode, it's hanging there and consumes huge temp space, so cancel that.
