[GENERAL] number of elements in a multidimensional array

[SunWuKung]

>From this array how could I get back the fact that this array consists
of a two dimensional array with X elements?

Select array_dims('{{1,4,10,11},{1,5,4,5}}'::text [])

I would like to get back the number 4 here?

Thanks for the help.
