Is there a function reference for Postgresql anywhere? I can't find one
in the standard documentation.

Yes, I've seen that. But when I type \df in psql it lists a lot more
functions than are described on those pages. What do oid() or
likejoinsel() do, for instance?

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.
