If you drop a table that someone else has recently used, the someone
else's backend is probably still holding the file open. We generally
don't close open file descriptors until we have to.

In current sources I think that you'd get a "cannot unlink" NOTICE,
but the table would get logically dropped anyway, and the sole
side-effect would be failure to recover the disk space. But in this
case we could be talking about large amounts of disk space.
