Re: VACCUM FULL ANALYZE PROBLEM

But I need to do full vacuum because I deleted some of the fields that are
not use anymore and I also add another fields. Is there

another way to speed up full vacuum?

Hi,

just make sure that your freespace map is big enough and then do a vacuum
analyse without the full option.

I can imagine that database performance might not be as good as it would be
after a vacuum full, though I expect that it wouldn't make much difference.

Hi,

I have 3 tables in the database with 80G of data, one of them is almost 40G
and the remaining 2 tables has 20G each.

We use this database mainly for query and updating is done only quarterly
and the database perform well. My problem

is after updating and then run VACCUM FULL ANALYZE vacuuming the tables
takes days to complete. I hope someone

can help me solve my problem.

Thanks
