I wonder if this remark in the release notes is relevant. Tom will
probably shed some light here. I don't get the connection but we'll

* Improve handling of cases where PL/pgSQL variable names conflict with identifiers used in queries within a
function (Tom Lane)
The default behavior is now to throw an error when there is a conflict, so as to avoid surprising behaviors. This
can be modified, via the configuration parameter plpgsql.variable_conflict or the per-function option #
variable_conflict, to allow either the variable or the query-supplied column to be used. In any case PL/pgSQL will
no longer attempt to substitute variables in places where they would not be syntactically valid.
