Обсуждение: why do we have rd_istemp?

Given "Relation rel", it looks to me like rel->rd_rel->relistemp will
always give the same answer as rel->rd_istemp.  So why have both?

Might be historical --- relistemp is pretty new.

Is this a TODO or something we want to clean up?

Doesn't strike me that it's worth the amount of code that would have to
change.  rd_istemp is known in a lot of places.  Replacing it with a
double indirection doesn't seem attractive anyway.
