It sounds to me like you've got serious disk problems --- losing a
couple hundred thousand rows is not normal :-(. The index complaint
also suggests on-disk corruption --- it means that the btree version
information that's stored in the first page of a btree index wasn't
right.

How exactly did you "shut down the server"? Have you noticed any other
evidence of disk problems, outside Postgres?
