If that's the case, I would recommend to add at least something in the

No need for it in the backend, unless there are plans to switch from
processes to threads there :p

libpq, ecpg and anything using them have to care about that.  Worth

CRYPTO_get_id_callback() and that it tracks the number of opened
connections.
