I don't think so. libpq only uses a timeout in that function when
it's making a connection to the server and a connect_timeout has been
specified in the connection parameters. You're showing an error that
seems to have occurred on an already-live connection (although maybe
I'm misinterpreting that).
If it is libpq, the answer is you're using an unreasonably tight
connection timeout. But that's hardly an unusual error message;
have you eliminated the possibility it's coming from some other
code entirely?
