To clarify a bit: there's more than one problem here. Amit added an
open item about pre-existing leaks related to rd_partcheck. (I'm going
to review and hopefully push his fix for that today.) However, there's
a completely separate leak associated with mismanagement of rd_pdcxt,
as I showed in [1], and it doesn't seem like we have consensus about
what to do about that one. AFAIK that's a new bug in 12 (caused by
898e5e329) and so it ought to be in the main open-items list.
This thread has discussed a bunch of possible future changes like
trying to replace copying of relcache-provided data structures
with reference-counting, but I don't think any such thing could be
v12 material at this point. We do need to fix the newly added
leak though.
