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
think.

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.

Thanks Ewan & Tom. Yes, the docs describing PQnotifies() suggests the usage
of select(), but lacks a pointer to PQsocket(). This would be a helpful
addition.
Cheers!
