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.

 

regards

Iain

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
