Interesting corner case. The proposed fix seems not very consistent
with the way we handle comparable cases elsewhere, though. In general,
md.c will cut some slack when InRecovery if a relation is shorter than
expected, but not if it's not there at all. (This is, indeed, what
justifies mdtruncate's response to file-too-short...) We handle
dropped files during recovery by forced smgrcreate() in places like
XLogOpenRelation. I'm inclined to think smgr_redo should force
smgrcreate() before trying to truncate.
