Hello,
just a question regarding multidimensional arrays.
When i create an array, its number of dimensions is recorded in
pg_catalog.pg_attribute (attndims), but they are not enforced upon insertion,
nor is this presented by \d command. (i didn't see any attndims column showing
up in the logs)

Any reasons why this is so?

Hey Achilleas,

"The current implementation does not enforce the declared number
of dimensions either. Arrays of a particular element type are all
considered to be of the same type, regardless of size or number
of dimensions. So, declaring the array size or number of dimensions
in CREATE TABLE is simply documentation; it does not affect run-time
behavior."
