Yeah. I had been wondering about long-lived open transactions, but AFAICS
from the code, backends should re-read the config file at the next client
command submission, whether inside a transaction block or not. So the
thing to look for is what might be overriding the config file's value.
In interactive sessions, examining the pg_settings view would be a
promising way to debug that. I suspect though that the OP is guessing
about what's happening inside application-driven sessions, where it would
be hard to do that kind of debugging :-(

As an aside the alter user/database commands do end up requiring the user to disconnect and reconnect. Is there a hard limitation why an administrator can't send some kind of signal to cause a re-read of those by an active session?
