How to write a new tuple into page?
Hi, I'm trying to construct a new tuple type, that's not heaptuple,
When I get a tupleTableSlot, I will get data info from it and then I
will constuct a new tuple, and now I need to put it into a physical
page, how should I do?

Postgres writes table pages from shared buffers/buffer pool to disk
via storage manager (smgr.c). I think looking at the code around
FlushBuffer()/FlushRelationBuffers()/smgrwrite() might help.
