idle means its NOT executing any query... thats just the LAST query it
executed. idle in transaction means someone/something started a
transaction but isn't actively doing anything so there's a pending
transaction thats idle.
backend_start | 2015-04-06 20:55:07.921089-07
this client connected on that date/time
xact_start | 2015-04-06 21:16:26.820822-07
the transaction started at that date/time (about 21 minutes after
creating the connection)
query_start | 2015-04-06 21:16:26.834017-07
the last query started about 0.014 seconds after creating the transaction

the state_change to idle-in-transaction took place about 0.0001 seconds
later (so the insert took all of a millisecond).
What date/time was it when you did that select from pg_stat_activity
? thats how long this transaction has been pending, which if its more
than a few seconds to at most a minute, is almost certainly a 'very bad
thing' unless the transaction is actively crunching data.
if you're using a client such as JDBC which autowraps queries in
transactions by default, you need to invoke COMMIT's when you're done
doing that unit of work.
