Yeah, very standard: add it to the code. ;) There are no "hooks" for
that kind of access control currently. I'm not aware of a Scheme
system (except possibly Guile, just because it has everything else:)
that has such.

Probably start off untrusted and add trusted afterward--I'd like to
get the basics (interface between Scheme and PG datatypes, SPI glue) in
place and get familiar with the code. It shouldn't be too hard to add
a "capability mask" to the interpreter structure and put permission
checks in.
