pg_import_csv_to_heroku.sh

# You have your csv data and it looks like so... It's in a file named "my_data.csv" and we want to import it into a table named "my_things".

"1", "Something", "0.50", "2013-05-05 10:00:00"
"2", "Another thing", "1.50", "2013-06-05 10:30:00"

# Now you want to import it, go to the command line and type:

$ PGPASSWORD=PWHERE psql -h HOSTHERE -U USERHERE DBNAMEHERE -c "\copy my_things FROM 'my_data.csv' WITH CSV;"

# Voila! It's impoted. Now if you want to wipe it out and import a fresh one, you would do this:

$ heroku pg:psql
$ TRUNCATE table my_things;

Now re-do the PGPASSWORD command above:

$ PGPASSWORD=PWHERE psql -h HOSTHERE -U USERHERE DBNAMEHERE -c "\copy my_things FROM 'my_data.csv' WITH CSV;"
