Thanks, that was it exactly. PGAdmin session opened for a week. Argh. Gotta have some conversations with some folks.Do you guys have any kind of regular monitoring in place to flag users who don't politely close their connections?
pg_stat_activity view would do the trick for you.
Search for the connections that are running long for more than a few hours ? or days ?
See if any idle in transactions that have now() - state_change, more than a few mins ? or hours ? or days ?
