Elements of string array are wrapped in single quotes

[konovalov-maksim]

I faced an issue while trying to read from string array. Selected string elements are wrapped in single quotes

Reproducing

Clickhouse

create table example_ch
(
    array_of_strings_field Array(String)
)
engine = MergeTree PRIMARY KEY array_of_strings_field;

insert into example_ch (array_of_strings_field) values (['foo', 'bar']);

Postgres

create foreign table example_pg
    (
        array_of_strings_field text[]
     )
server clickhouse_server
options (database 'clickhouse_db', table_name 'example_ch', engine 'MergeTree');

select array_of_strings_field[1] from example_pg;

Expected output:
foo
Actual output:
'foo'
