Re: wiki on monitoring locks has queries that don't seem to work

So I'm running 8.4 and go to this
page:http://wiki.postgresql.org/wiki/Lock_Monitoring

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.

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.
