Yes, once I have the select outputting it to CSV is not a problem. As you say PG handles that nicely.
Thx

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.
