Patch implementing that attached. I named the function "ReadOrZeroBuffer".
We already have an API quirk similar to this: relation extension. It
seems strange to have two different kinds of special case API that are
used alongside each other in XLogReadBuffer()
Currently if we extend by a block we say
buffer = ReadBuffer(reln, P_NEW);
Why not just add another option, so where you use ReadOrZeroBuffer we
just say
buffer = ReadBuffer(reln, P_INIT);
Because ReadOrZeroBuffer needs the block number as an argument.
