The solution is paraphrased here: Create your table: CREATE TABLE zip_codes (ZIP char(5), LATITUDE double precision, LONGITUDE double precision, CITY varchar, STATE char(2), COUNTY varchar, ZIP_CLASS varchar); Copy data from your CSV file to the table: COPY zip_codes FROM ‘/path/to/csv/ZIP_CODES.txt’ WITH (FORMAT csv);
Do you want the resulting file on the server, or on the client?
