Printer for "SET configuration_parameter FROM CURRENT"

[bolajiwahab]

PostgreSQL support this syntax for setting configuration:

SET configuration_parameter { TO value | = value | FROM CURRENT }

Currently there is no printer for this syntax even though it is valid syntax and we simply raise NotImplementedError.
We could do:

if node.kind == vsk.VAR_SET_CURRENT:
    output.write('FROM CURRENT')
elif node.kind == vsk.VAR_SET_VALUE:
    output.write(' TO ')
    output.print_list(node.args)
elif node.kind == vsk.VAR_SET_DEFAULT:
    output.write(' TO ')
    output.write('DEFAULT')
elif node.kind == vsk.VAR_SET_MULTI:
    pass

Thanks for finding and reporting the defect! Will cure the problem... if you do not beat me with a PR 😉

Thanks. You can have a look at the PR #168. Looks like tests are not running though.
