date arithmetic

Hi ALL,

I want to do date arithmetic in SQL with a column that is integer.

example

create table bob ( col1   timestamp
, col2   int4
;

where col2 represents a number of minutes.


I want to do something like

select col1 + interval col2 minutes from bob

This is doable with most other RDBMS (DB2, Oracle MS SQL) what am I
missing??

I know one option is to create col2 as interval, but does not work for me.
How can I cast int4 to "interval minutes"
