Thank you for looking at this!
I'm also bothered by errors "no empty local buffer available" produced (on master, but not on REL_12_STABLE) when inserting larger tuples: INSERT INTO t SELECT '' FROM generate_series(1, 500) g; INSERT INTO t SELECT (SELECT string_agg('text' || g, ' ') FROM generate_series(1, 700) g) FROM generate_series(1, 30);
Are those errors expected?
I think it is expected. More local buffers need here. I set temp_buffers to 2GB.
this error didn't report. But stack depth limit exceeded. It is a hint that to process
