+2) Launch pgbouncer in foreground mode to see if everything 
+   is ok:
+
+   # install -d -o _pgbouncer /var/run/pgbouncer
+   # pgbouncer -u _pgbouncer /etc/pgbouncer/pgbouncer.ini

+PgBouncer is a lightweight connection pooler for PostgreSQL.
+
+Features:
+* Several levels of brutality when rotating connections:
+  + Session pooling
+Most polite method. When client connects, a server connection will
+be assigned to it for the whole duration it stays connected. When
+client disconnects, the server connection will be put back into
+pool. This mode supports all PostgeSQL features.
+  + Transaction pooling
+Server connection is assigned to client only during a transaction.
+When PgBouncer notices that transaction is over, the server will be
+put back into pool.  This mode breaks few session-based features of
+PostgreSQL. You can use it only when application cooperates by not
+using features that break. See the table below for incompatible
+features.
+  + Statement pooling
+Most aggressive method. This is transaction pooling with a twist -
+multi-statement transactions are disallowed. This is meant to
+enforce "autocommit" mode on client, mostly targeted for PL/Proxy.
+
+* Low memory requirements (2k per connection by default). This is due to
+the fact that PgBouncer does not need to see full packet at once.  
+* It is not tied to one backend server, the destination databases can reside 
+on different hosts.  
+* Supports online reconfiguration for most of the settings.
+* Supports online restart/upgrade without dropping client connections.  
+* Supports protocol V3 only, so backend version must be >= 7.4.
