Hi,

Thanks for your new patch.

Failed regression test.
It's necessary to change the first a in “allowed step characters are” to 
uppercase A in the regression test of 002_pgbench_no_server.pl.

The behavior of "g" is different between v12 and the patche, and 
backward compatibility is lost.
In v12, BEGIN and COMMIT are specified only by choosing "g".
It's a problem that backward compatibility is lost.

When using ( and ) with the -I, the documentation should indicate that 
double quotes are required,
and  "v" not be able to enclose in ( and ).

Regards,
