Hi Tom,
thank you for your thoughts. There are two reasons for choosing an
int4-only version. I am not familiar with postgres development (yet) and
i was not sure how open you are about such changes to core and if the
proposed feature is considered valuable enough to go into core. The
second reason was ease of implementation. The intarray extension does
not allow any NULL elements in arrays and treats multidimensional arrays
as though they were linear. Which makes the implementation straight
forward, because there are fewer cases to consider.
However, i will take a look at an implementation for anyarray in core.
