Re: Changing the state of data checksums in a running cluster

As the resident perl style pedant, I'd just like to complain about the
below:

This breaking between the command line options and its arguments is why
we're switching to using fat commas. We're also using long options for
improved self-documentation, so this should be written as:

    PostgreSQL::Test::Utils::system_or_bail('pg_checksums',
        '--pgdata' => $self->data_dir,
        '--enable');

And likewise below in the disable method.
