The \df listing shows a lot of functions that have internal purposes, like
casting functions (oid(), int4(), varchar(), ...), selectivity estimation
(likejoinsel), functions behind operators (int4pl, oideq), transition
functions for aggregates, indexing functions, etc.
All the user-space functions should be documented at that URL.
