Hi Tom,
I think I understand now.
Postgres type system does not distinguish between array types with different
number of dimensions. int[], int[][] and int[][][][][][] are all equivalent
to the type system.
Number of dimensions is part of the value though and execution takes care
of it.
If I sub
rrect value when
column is defined using _ form?
Best,
Piotr

Hi,
As documented to
https://www.postgresql.org/docs/11/arrays.html#ARRAYS-DECLARATION one can
create column of an array type using `[]` form.
Internally, array types get a name in the form of `_`.
This is documented
