creating array of integer[] out of query - how? - Mailing list pgsql-general

Hello,

if I use this statement:

postgres=# select array[[2,3],[3,4]];
     array
---------------
 {{2,3},{3,4}}

-> the result looks for me as an array of integer-arrays

now I try:

select array(
select a from
(
select array[2,3] as a
union

select array[3,4] as a
) x);

and the result is:

FEHLER:  could not find array type for datatype integer[]

Is there a bug in my thinking that array[[2,3],[3,4]] really constitutes an array of integer[],

or is there any cast missing,

or is a bug anywhere else?

Best wishes,

Harald
