I seem to have painted myself into a corner, technologically speaking.
I am implementing a database using embedded SQL, and PostgreSQL
6.5.3 as the backend. The problem is that I would like to use the NOTIFY
feature, but the only way I've found of doing this from within a C
program is to use the 'PQnotifies()' function, which requires a PGconn
connection its first parameter. ESQL doesn't provide this connection
information as far as I can tell.
So, it appears that I can set up my program to LISTEN or
UNLISTEN using embedded SQL, but I can't get a notification when
it's sent. Or so I think. _Is_ there a way to get the libpq connection info
from the ESQL CONNECT call?
Does anyone have a suggestion (other than completely rewriting
my application in libpq calls)? Pointers to any examples of how
this is done would be especially helpful, but any hints would be
appreciated.
