> Oftentimes people try to write queries like
> SELECT *
> FROM table
> WHERE ds = 2011-08-03
> This won't work because quotes are missing, and it'll actually try to filter on ds =
"2000".
> People run into this pretty regularly; a simple check on whether the types match exactly
in partition predicates would make this a lot less likely to happen.
