Howdy!

This query is coming from PgPool I believe.

SELECT count(*) FROM pg_catalog.pg_class AS c WHERE c.relname = 'import_jobs' AND c.relpersistence = 'u'

This is a very small database, like 10/15 tables, it's basically empty.  
If i run this query manually, it comes back immediatly. 
However according to this it's been running for about an hour.

v3=# select now();
              now

query            | SELECT count(*) FROM pg_catalog.pg_class AS c WHERE c.relname = 'import_jobs' AND c.relpersistence = 'u'

(I actually restarted the application and now there are 4 of these)

Any idea why the query would hang like this?

I don't see it waiting on locks or anything like that.

any ideas?

Thanks
