A geometry column is only a type like integer or text for postgresql.

Thanks Chris,

However maybe better question will be can spatial and non-spatial data be saved in one PostgreSQL table? Precisely, is it possible to have table with some spatial columns (geometry
columns) and with some 
ordinary columns (non-spatial) and is it good practice?
>From your answer i can conclude that it is possible to have table without spatial data that refers to some spatial table through foreign key?
