Re: How to just "link" to some data feed

Hello.

I'd recommend you to have some intermediate (tem****ary?) table to load 
data to and then sync data to main table using simple insert statement.
The call list would look like
copy  temptbl FROM '/tmp/codigos_postales.csv' DELIMITERS ',' CSV;
insert into maintbl select * from temptbl where cp not in (select cp 
from maintbl)
delete from temptbl;
commit;

P.S. Last step is not needed if you use tem****ary table.
