I think this is a good problem to attack, but the proposed patch seems
a bit narrow and brute-force. Surely this isn't the only place where
we're missing an errposition pointer on a "no such schema" error?
It's probably not reasonable to add a pstate argument to
LookupExplicitNamespace itself, given that namespace.c isn't part
of the parser. But you could imagine adding an interface function
in the parser that calls LookupExplicitNamespace and then throws a
position-aware error on failure, and then making sure that all schema
lookups in the parser go through that.
