What *kind* of SQL error would trigger the cleanup? I've certainly had
numerous SQL errors prior to this problem showing up (parse errors, misnamed
attributes, ...), but that didn't apparently fix the problem system wide.
Also, are these buffer counts per backend or per postmaster? In other words,
does a particular kind of SQL error need to occur on each backend?
