PostgreSQL 11 Administration Cookbook

How to do it…

The basic way to ensure that we get all commands successful or none at all is to literally wrap our script into a transaction, as follows:

BEGIN;command 1;command 2;command 3;COMMIT;

Writing a transaction control command involves editing the script, which you may not want to do or even have access to. There are, however, other ways as well.

From psql, you can do this by simply using the -1 or --single-transaction command-line options, as follows:

bash $ psql -1 -f myscript.sqlbash $ psql --single-transaction -f myscript.sql

The -1 option is short, but I recommend using --single-transaction, as it's much clearer which option is being selected.
