* format_function_signature: generate function name and argument list * * This is like format_function_arguments_old except that only a minimal * list of input argument types is generated; this is sufficient to * reference the function, but not to define it. * * If honor_quotes is false then the function name is never quoted. * This is appropriate for use in TOC tags, but not in SQL command
