When psql executes a script with the -f option, this additional option
will force the script to execute as a single transaction. Either all
SQL statements complete successfully, or no changes are applied.
When <application>psql</application> executes a script with the
<option>-f</> option, adding this option wraps
<command>BEGIN</>/<command>COMMIT</> around the script to execute it
as a single transaction. This ensures that either all the commands
complete successfully, or no changes are applied. (However, if the
script itself uses <command>BEGIN</> or <command>COMMIT</>, this
option will not have the desired effect!)
