I would start by looking at pg_locks to see if your update is blocked
by one of the connections which is idle in a transaction.  Any locks
won't be released until the idle transaction commits or rolls back.
Then look at pg_stat_activity to check timestamps.  Be sure your
software doesn't have any code path which leaves things dangling.
(Since you seem to be using Java, I recommend proper use of
try/finally blocks to ensure resources are released.)
