Thanks Jeff,
As I understand from your point, instead of connecting Postgresql port, try to use PgBouncer port.
I am using libpq library functions connect postgreql and code changes would be like this.
Previous code :
sprintf(conninfo, "user=%s password=%s dbname=%s hostaddr=%s port=%d", PG_USER, PG_PASS, PG_DB, PG_HOST, PG_PORT);
conn = PQconnectdb(conninfo);
new code:
sprintf(conninfo, "user=%s password=%s dbname=%s hostaddr=%s port=%d", PG_USER, PG_PASS, PG_DB, PG_HOST,
PG_BOUNCER_PORT);
conn = PQconnectdb(conninfo);

pgbouncer is designed to look (to the client) just like a normal postgresql server.
If you want all connections to the database to go through pgbouncer, you can move the real server to a different port,
andthen start up pgbouncer on that vacated port. In this case, the clients do not need to make any changes at all to
theirconfiguration.
If you want to keep the real server on the same port as it currently is and to use a special port to go through
pgbouncer,then you need to change the clients to use that new port number. You do this the same way you would change
theclient to use a different port if that different port were a regular postgresql server.
Cheers,
Jeff
