I have a query that is definitely blocked by another query. I run the
first or third queries, the ones that explicitly say that they're for
<9.2 and neither produces any output. The third query gives me a list
of 182 rows, only a few of which are actually locked in any meaningful
ways.
Those queries only find row-level locks, not object-level locks (as indicated). I suspect that you are blocking on object-level locks. Maybe you will have better luck with http://wiki.postgresql.org/wiki/Lock_dependency_information.
Now if I run this query:
select relname,pg_locks.* from pg_class,pg_locks where
relfilenode=relation and not granted;
I get the one row for the update / insert / delete that is getting blocked.
Can you show us that row?
Cheers,
Jeff
