Hi people,

This is not quite a pg question, but any suggestions are most welcome.

How can one query a list of values against a db field that contains a list of 
values ?

Table foo

foo_id | foo_name | da_list
1 | x | 1,2,3,4,5
2 | y | 1,4,5
3 | z | 4,5,11
4 | xyz | 14,15,33

As a result from another query I have parameter bar = '1,4' and want to find 
all rows from foo where da_list contains '1' or '4'. So loop over bar to loop 
over da_list in foo ?

My humble thanks,
