If this is a bug new in pg18, you should add an item to the "open items"
list here: https://wiki.postgresql.org/wiki/Open_Items  The RMT will
then take over and pester the committer/author to ensure the bug is
fixed.

If it's not new in pg18, then adding a commitfest entry in the "bug
fixes" category is the right thing.  I'd suggest to CC the committer and
author of the patch that caused the bug; with the amount of traffic in
pgsql-hackers these days, it's all but guaranteed that people will miss
things.
