nothing wrong?

Hi Hackers,
Here I have two questions related to extending a relation:
1. When we want a new page, we will do something like this:
LockPage(relation, 0, ExclusiveLock);
blockNum = smgrnblocks(reln->rd_smgr);
/* Try to locate this blockNum in buffer pool, but definitely can't? */
smgrextend(block
