And, since there's nothing new under the sun around here, we already had a discussion about that back in 2021: https://www.postgresql.org/message-id/flat/3471359.1615937770%40sss.pgh.pa.us That thread seems to have led to fixing some specific bugs, but we never committed any of the discussed valgrind infrastructure improvements. I'll have a go at resurrecting that... regards, tom lane
