Porting MySQL data types to PostgreSQL

["Gautam Sampathkumar" <gsampathkumar(at)gmail(dot)com>]

Hi,

   I am in the process of porting a MySQL database to PostgreSQL.

I was wondering why PostgreSQL does not support unsigned data types?

 

Does this mean I'd have to essentially double the space occupied by most database columns e.g convert mysql integer to postgresql bigint?

 

thanks,

Gautam
