The release notes for pg 13 advertise a new feature in
https://www.postgresql.org/docs/13/release-13.html#DDL-PARTITION-PRUNING
-

- But the manual still warns at
https://www.postgresql.org/docs/13/ddl-partitioning.html#DDL-PARTITIONING-DECLARATIVE-LIMITATIONS
BEFORE ROW triggers, if necessary, must be defined on individual
> partitions, not the partitioned table.

Looks like that "limitation" can go now? Or reduced to something like:
"BEFORE ROW triggers on the partitioned table cannot change which partition
is the destination."
