This was discussed previously, but rejected with the following argument:
There are some other disadvantages for making a function call. You
couldn't use that kind of literal in any other place where the parser
calls for a string constant: role names, tablespace locations,
passwords, copy delimiters, enum values, function body, file names.
Some of those appear to be very plausible use cases.
