Export remote Postgres table to CSV file on local machine I have read-only access to a database on a remote server. So, I can execute:

COPY products TO '/tmp/products.csv' DELIMITER ',';


But on that server I don't have permissions to create/save a file, so I need to do this on my local machine.

When I connect to the remote database, how can I execute a command to save the file on my local machine instead of the remote server?

Or, how can I execute a Linux command to connect to the remote database, execute a query, and save the output as a file to my local machine?
Both the approaches already suggested appear to be unnecessarily complicated.

Just use psql's built-in \copy command, which works just like server-side COPY but does a copy over the wire protocol to the client and uses client paths.

Because it's a psql backslash command you omit the trailing semicolon, eg:

\copy products TO '/tmp/products.csv' CSV DELIMITER ','


See the \copy entry in the manual for the psql command and the COPY command documenation for more detail.

Just like COPY you can use \copy with a (SELECT ...) query instead of a table name when copying data out (but not in).



A generally inferior alternative that can be useful in a few limited situations is to use:

psql -t -P format=unaligned -P fieldsep_zero=on -c 'SELECT * FROM tablename'


and use the -o flag or shell output redirection to write the output to a file. You should almost always use \copy in preference to this.
