What handle(s) would I need to feed to select() to wait for a notification
which I can then pickup via PQnotifies()?

PQsocket(conn), where conn is a pointer to your connection structure, I

PQsocket(connobject) delivers the file descriptor, or -1 if there is no
open connection.  There is some doco about this in the current
documentation set, although I have to agree it's terse.
