Open/read does not fail on invalid file

[dsoprea]

Recently I realized I was opening the wrong database and it took me an hour to figure it out because (*DB).FileSize() was returning non-zero and (*DB).Count() was returning zero, and there were no errors reported by (*DB).Open(). We have no standard way to figure out if the DB is invalid?

As a bonus, doing this will also change the target file even if it wasn't a correct/working database file to begin with.

Interesting, pogreb checks the file header when it opens the database file (https://github.com/akrylysov/pogreb/blob/master/db.go#L193), but it does it only for the index. I'll add an additional check, thanks for the report!

Your project had yet to be exposed to the right class of moron, and I'm here to help.
