Mmm ... seems like that just complicates matters. To make that useful,
you have to assume that there *is* a default table layout, it's
different across versions, and everything that looks at this GUC value
will know instantly what it is for each version. The last bit is kind
of a killer for tools like pgfouine, no? In any case I thought the
expectation here was that the default column list would be frozen at
what it is now, and probably will never change.
