Sure, but one hopes that someone writing PG_TRY is clued-in enough to
consider this issue. The thing that is worrying me here is that generic
STL code written by someone who never heard of Postgres is going to try
to make decisions about whether it can recover from an error thrown by
some part of the backend.
