Re: change bigint column to int

Mariel,

Just run a query and make certain that all values currently stored in the column fit in 4 bytes (+/- 2,147,483,648) before doing the ALTER.

Cheers,

Hi,

I want to change the column type from bigint to int to save space. By doing so, does it include some risks ? As I see it, I should only run vacuum full afterwards if I want to return space to the os right ?
