Hello Michaƫl,
The first failure is unrelated to the involved commits, as they touched completely different areas of the code: INSERT INTO hash_split_heap SELECT a/2 FROM generate_series(1, 25000) a; + WARNING: buffer refcount leak: [6481] (rel=base/16384/32349, blockNum=156, flags=0x93800000, refcount=1 1) And versions older than HEAD do not complain. Any thoughts?
Both animals use gcc experimental versions, which may rather underline a new bug in gcc head rather than an existing issue in pg. Or not.
