I think that anything we want to add should either go before SET or
after the value, such as:
ALTER SYSTEM SET configuration_parameter = 'value' IN FILE 'myconf.conf';
ALTER SYSTEM CONFIGURATION FILE SET configuration_parameter = 'file';
ALTER SYSTEM CONFIGURATION FILE 'myconf.conf' SET
configuration_parameter = 'file';
I agree we shouldn't back ourselves into a syntactic corner.
