Description:
I have PostgreSQL 13. Let's declare the type below, then use it in
pl/pgsql:
create type typ1 as (
fld1 int[][]
);
do $$
declare
a typ1;
begin
a.fld1 = '{{121,122,123,124}}'; -- OK
(1)
a.fld1[1] = '{221,222,223,224}'; -- fails
(2)
a.fld1[1][1] = 321; -- OK
(3)
a.fld1[1][2] = 322; -- OK
unless line (1) is removed
end;
$$;
In line (2) the plql reports ERROR: invalid input syntax for type integer:
"{221,222,223,224}"
When lines (1) and (2) are removed, psql reports ERROR: array subscript out
of range
Is this expected behavior? Why?
