Really? Didn't knew that.
Consider:
1) I add 2 pages to the newly-created relation
using P_NEW as BlockNumber;
2) then I do LockRelationForExtension; ReadBuffer(135) and
UnockRelationForExtension.
What BlockNumber will be assigned to the buffer, if I call
ReadBuffer(P_NEW) now? 136?
BTW, is it OK to say "BlockNumber is assigned to buffer"?

TIP 9: the planner will ignore your desire to choose an index scan if your
joining column's datatypes do not match
