Yeah, the only part that's even a bit hard to replicate in userland is
initializing the autoloading mechanism in each session. It would be
cleaner to provide a feature similar to what you describe that could
be used for that purpose as well as others. However, where does the
"parameterless function" come from? Is it a regular PLv8 (or for this
purpose PL/Tcl) function expected to be present in pg_proc?
