I ask postgres to format it for me instead of relying on psql

psql db_name  -c "copy (select * from foo ) to stdout;" 

this gives me postgres style tab separated values, but I can 
have CSV (or any otther format COPY can do) if I want.
I usually use a more complex subquery with a list of columns and 
expressions, where,  order by clauses, etc... )

I use this in a script that pulls data from one database and inserts
in into another.

Requires postgres 8.2 or later
