int8 arrays parsed as numbers, float arrays parsed as strings

[strk]

I was testing the recent numeric parsing and found out that:

1. int8 is parsed as string, but _int8 is parsed as an array of numbers (should be strings)
2. int4 is parsed as number, but _int4 is parsed as an array of strings (should be numbers)
3. float8 is parsed as number, but _float8 is parsed as an array of strings (should be numbers)

This is the default as of version 2.6.2

Ah, yeah that's yucky. I didn't modify the array parsing when I switched things back over to the more pedantic type parsing.

@brianc seems like this was resolved by #501?

(Just eyeballing the diff; haven't actually verified.)

Yeah you're right! thanks. :)
