This stack trace is pretty wacko; in particular, frames 13-17 imply that
you've got a Query whose jointree field is pointing directly at an
AccessPriv node, and then the AccessPriv node's cols field is pointing
directly at a BoolExpr. None of that makes any sense at all. The most
likely explanation is that the debugger is not telling the truth (perhaps
you've pointed it to the wrong executable?), in which case there's exactly
zero trustworthy information here.
A different line of theorization is that the querytree read back from the
system catalogs for the view that's evidently getting expanded is corrupt
somehow. You might look at whether psql's \d+ on the view produces a
sane-looking query.
Please see if you can extract a reproducible test case. It's not very
likely that anybody will be able to help on the strength of the
information you have provided.
