This is a psql directive to urn off output alignment.

Don't show column headers or the row count

Redirect output to the named file

Read the system catalog for a list of relations and construct a GRANT
command for each one to give ALL access to user joe. The output looks
like this:

GRANT ALL ON prod.address TO joe;
GRANT ALL ON prod.address_id_seq TO joe;
GRANT ALL ON prod.address_telephone TO joe;
GRANT ALL ON prod.area TO joe;
...

and is written into the file /tmp/grant.sql as directd earlier.

Stop sending output to the file.

Run the output file as a script, thus granting the permissions to joe.
