Looking through the code, the bms_add_member() call in
logicalrep_read_attrs() does not use the usual
FirstLowInvalidHeapAttributeNumber offset, so that seems like a possible
problem.

However, I can't quite reproduce this.  There are various other checks
that prevent this scenario, but it's plausible that with a bit of
whacking around you could hit this error message.
