Because i always query the whole row, and in the other way(many tables) i will always join + have other indexes.

Why do you think you need an array of theType v. a dependent table of theType. This tack is of course immune to to most future type changess.

Interesting.  Of course any decent mapper will return "the whole row". And would it be less disk intensive as an array of "struct ( where struct is implemented as an array)".  From other threads [1] [2] I've come to understand the datatype overhead per native type will be applied per type instance per array element.

[1] 30K floats
[2] char array
