Add support for Postgres VARCHAR array columns

my test table(postgresql):
CREATE TABLE public.arr_test(
id serial,
content text,
films integer[] NULL,
films_relation jsonb NULL,
imgs varchar(256)[] NULL,
primary key(id)
);
warn log:
Unexpected JDBC type '2003' for column 'imgs' that will be ignored [io.debezium.relational.TableSchemaBuilder]

I looked at the code in PostgresValueConverter.java, varchar array seems to be unrealized.
case PgOid.VARCHAR_ARRAY:
.....
      // These array types still need to be implemented. The superclass will not handle them so
      // we return null here until we can code schema implementations for them.
      return null;

Would like to ask why varchar array is not supported. Is it recommended to use the text array?
