In https://www.postgresql.org/message-id/flat/3DPLMQIC.YU6IFMLY.3PLOWL6W%40FQT5M7HS.IFBAANAE.A7GUPCPM we'd concluded that the issue is probably that postgres_fdw has no logic to shut down its external connections when the session closes. It's not very clear why the SSL dependency, but we speculated that adding an on_proc_exit callback to close the connection(s) would help. I imagine dblink has a similar issue. regards, tom lane
