Hi all,

Any help on the following would be greatly appreciated, every evening
most of the data on our postgres 8.1 install is deleted and then a new
set of data is imported into the database (around 100 million row).
After this takes place we run a Vacuum Analyse on the whole database.

Last night I got the error

Error Relation 41036649 deleted while still in use

There are other queries running on the database at the time of the
Vaccum but I was under the impression a Vacuum Analyse only removes
deleted / unused tuples etc. Is this not correct ?

Is there anyway I can see what relation 41036649 was before it was
deleted

Thanks for all the help

Francis
