I agree, that should work like you expect. I just pushed a fix.

Hi all,
Using 6.0.1. I just painfully discovered that
(pg-array->list (list->pg-array (list)))
=> ERROR
pg-array->list: expected argument of type <pg-array of dimension 1>;
given: (pg-array 0 '() '() '#())
The documentation for list->pg-array states that it produces an array
of dimension 1. However, if you pass an empty list, you get back an
array of dimension zero which you then can't transform back to a list [
except by going straight to the internal vector ].
My question is, "shouldn't these conversions be symmetric?" I
understand an array with no elements is meaningless as an array, but
Postgresql (ab)uses arrays as substitutes for lists and sets, so an
empty array does have meaning.
Just a thought.
Thanks,
George
