[postgis-users] quick ps/sql question on how to fill multipoint object best

[Biddy]

Hi everyone,

I'm sorry for the newbie question, but I am not very experienced with  
ps/sql (yet).

I have values in one table (data just in numerical types, no spatial  
types) and I want to fill another table with them that contains  
several multipoint columns.

I want a multipoint to contain around 300 points.
I wonder how best to do that quickly in ps/sql.

Many thanks,
B.
