I checked it and I did not find any log running sql or any open transaction. Not even in pg_prepared_xacts.
And it looks like pg_catalog database is making the alarm.
Any other idea please, where I need to look into.
Thanks.

Hi,
I am running Postgresql 9.1 and I can see the datfrozenxid is going high

The above seems to be the contributing factor.
Does:
select * from pg_stat_activity
show long running queries.--

I vacuum database manually but nothing is working out.
Please help,
