Still working on this problem. I have reached my max connection
counts, which I set to 100, and it seems like I have 100 "idle in
transaction" connections.  And from the pg_stat_activity table I can
see that they are all stuck on this sql.  I wonder if anyone can point
me to where this sql originates.  That might help me determine the
reason why it is getting stuck.
