importccl: cannot load array data with IMPORT PGDUMP

[rytaft]

While doing QA for , I tried to load a table with some array data:

CREATE TABLE public.t1 (
    x integer[],
    y integer[]
);

The table was created successfully, but there was an error when trying to load array data:
pq: nodelocal:///single.sql: insert row: value type string doesn't match type ARRAY of column "x"

Array data in Postgres is wrapped in quotation marks like this: '{1}', '{{2,3},{4,6}}'
