Hello
I am not sure so decrease of array dimensions is regular operations.
But following code dont make syntax error.
create or replace function xxx() returns bool as $$
declare v1 varchar[]; v2 varchar[][];
begin
v2 := array[array[1,2], array[3,4]];
raise notice 'v2 %', v2;
v1 := v2[1];
raise notice 'v1 %', v1;
return 't';
end; $$ language plpgsql;
I expect v1 = [1,2], but v1 is null.
What is wrong?
Regards
Pavel Stehule
