That's talking about builtin functions, ie functions implemented by
statically-linked routines in the standard backend. The SQL name is
now distinct from the C-language name, but that wasn't true before 6.5.
I kind of thought you had seen this and realized it would be a good
idea to have the same functionality for dynamically linked routines.
If you came up with the idea independently, it must clearly be a good
thing ;-)
