Depending on your use case, this may be a better way:

In psql:
=> \copy (select col1,col2,col3 from data) TO data.csv CSV HEADER

or on the command line:
$ psql -c '\copy (select col1,col2,col3 from data) TO data.csv CSV HEADER'

Strictly speaking, the CSV formatting isn't being done in the database
but rather by psql.
