Something like:

That assumes that ref_id is null. It would help to see your table structure

character string then you might need ref_id='' or coalesce(ref_id,'')='' if

Hi folks,

If I create a binary cursor on a recent version of PostgreSQL, how can I
tell if the timestamp data internally is an 8 byte double or an 8 byte
integer?
I see an #ifdef that changes the code path to compute timestamps as one
type or the other, but I do not know how to recognize the internal

Make sure you have stats collector enabled, if auto vacuum is doing the
analyze and vacuum it should be recording that info in this view. For
details on this you can have a look at -->

Hi,

changes to what the autovacuum daemon logs, how can we verify it's doing its

don't see that in the system catalog.
