You are right. That was the problem. I tried the query from http://wiki.postgresql.org/wiki/Lock_Monitoring and found a COMMIT transaction that was blocking it.
I restarted postgresql again, and (it seems) everything went back to normal. Was there another way to unlock the table then?

Subject: [GENERAL] simple update query stuckBoth queries are "waiting". Your table must be locked.Hello,
I'm using postgresql 9.0.13, and I have a simple query that seems to be stuck. I did a
postgres=# select procpid, query_start, waiting, current_query from pg_stat_activity;
procpid | query_start | waiting | current_query
32605 | 2014-04-01 12:39:46.957666-07 | t | UPDATE public.GL_ACCOUNT_ORGANIZATION SET ROLE_TYPE_ID=$1, FROM_DATE=$2, THRU_DATE=$3, POSTED_BALANCE=$4, LAST_UPDATED_STAMP=$5, LAST_UPDATED_TX_STAMP=$6, CREATED_STAMP=$7, CREATED_TX_STAMP=$8 WHERE GL_ACCOUNT
_ID=$9 AND ORGANIZATION_PARTY_ID=$10

As you can see this is a pretty simple update query, but it's been running 24 minutes in one thread and nearly 10 minutes in the other thread. What's also strange is it's not trigger a transaction timeout either.
I've already re-started the database recently, and there's not too many threads executing -- just 38 threads total. Is it possible that the table is corrupted or needs repair?
