pg_get_functiondef would produce more than we want, but it looks like
pg_get_function_sqlbody() would do.
BTW, while researching this I noted the header comment for
pg_get_functiondef:
* Note: if you change the output format of this function, be careful not
* to break psql's rules (in \ef and \sf) for identifying the start of the
* function body. To wit: the function body starts on a line that begins
* with "AS ", and no preceding line will look like that.
Needless to say, the SQL-function-body patch has ignored this advice
totally. At the very least this comment needs to be adjusted, but
I wonder if it's not telling us that \ef and/or \sf are broken.
