I'd wonder if it'd be better to have a set of literal formats and "input"
functions like to_guid(text, text) for more complicated cases. The broader
we make the literal format, the harder it is to determine if the input
actually is what was intended. For example, did the user mean to put that
ipv6 address in this guid column and what about this other ipv6 address
looking thing which is abbreviated, are we putting in what the user
expects?
