I wanted to call out that if there's a connection pooler (e.g.
PgBouncer) in the middle, then BACKEND_PID (and %p) are incorrect, but
pg_backend_pid() would work for the query. This might be an edge case,
but if BACKEND_PID is added it might be worth listing this edge case
in the docs somewhere.
good note
This patch is marked RFC, but given the comments upthread from Tom, Andres and Peter, I think it should actually be Rejected.
