Well, this is not a bug as such, so it's very unlikely that a fix like
this will be back-patched. Also, if this becomes an issue only for
more than over 1000 partitions, then it's not very relevant for PG 10
and PG 11, because we don't recommend using so many partitions with
them. Maybe we can consider fixing PG 12 though.
Thanks,
