Using array_agg results in a string

[robertsmit]

When querying something like
SELECT Array[1,3] as col1

just results in a row with a vector.

But when using something like:
Select array_agg(t.textval) as col1 from table t group by true
Give me a string.

Is this a known issue. I expect to get a Vector as col1 result.

saw something about that it only works for integers.

Yes I think that linked issue (#58) covers the feature request, since array_agg does work on integers:

julia> execute(conn, "SELECT array_agg(t.ns) FROM (VALUES (1),(2)) AS t (ns);")[1,1]
2-element Vector{Union{Missing, Int32}}:
 1
