WIP Alert This is a work in progress. Current information is correct but more content will probably be added in the future.
load CSV file into a table
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' DELIMITER ',' CSV;
If your CSV file has a HEADER row you wish to ignore, use this slightly modified command instead:
COPY zip_codes FROM '/path/to/csv/ZIP_CODES.txt' DELIMITER ',' CSV HEADER;
