Hi Gnanam,
I assume your not ending your transactions with commit or rollback. When
using a connection pooler your connection is reused for next request. So
if one request does something that initiates an implizit BEGIN (like an
UPDATE/INSERT) without a COMMIT or ROLLBACK this connection remains in
IDLE IN TRANSACTION mode. Please ensure that you invoke a COMMIT after
each successful request or ROLLBACK after failed or control these inside
your application. I'm not familiar with pgpool but check if you can
configure your pooler for this behaviour
