JOOQ 以 PostgreSQL 自定义类型作为数组失败：错误：格式错误的记录文字

Question

我在 Postgres 上有以下自定义类型：

CREATE TYPE my_custom_type AS (
 field_a VARCHAR,
 field_b NUMERIC(10,3)
 );

还有下表：

CREATE TABLE my_table
(
 COL1 VARCHAR(120) NOT NULL,
 CUSTOM_COLUMN  my_custom_type,
 CUSTOM_COLUMN_ARRAY my_custom_type[]
);

当我将自定义类型与 JOOQ 一起使用时，一切正常：

@Test
public void testWithoutArray(){
    MyTableRecord record = dsl.newRecord(MyTable.MY_TABLE);

    record.setCol1("My Col1");
    MyCustomType customType = new MyCustomType();
    customType.setFieldA("Field A Val");
    customType.setFieldB(BigDecimal.ONE);
    record.setCustomColumn(customType);

    record.store();
}

但是，当我尝试在映射到自定义类型数组的字段中设置一些值时，出现以下错误：

@Test
public void testWithArray(){
    MyTableRecord record = dsl.newRecord(MyTable.MY_TABLE);

    record.setCol1("My Col1");
    MyCustomTypeRecord customType = new MyCustomTypeRecord();
    customType.setFieldA("Field A Val 1");
    customType.setFieldB(BigDecimal.ONE);

    MyCustomTypeRecord customType2 = new MyCustomTypeRecord();
    customType2.setFieldA("Field A Val 2");
    customType2.setFieldB(BigDecimal.TEN);

    record.setCustomColumnArray(new MyCustomTypeRecord[]{customType, customType2});
    record.store();
}

org.jooq.exception.DataAccessException: SQL [insert into "my_table" ("col1", "custom_column_array") values (?, ?::my_custom_type[]) returning "my_table"."col1"]; ERROR: malformed record literal: "my_custom_type"(Field A Val 1, 1)"

JOOQ debugg 生成的查询如下：

DEBUG [main] org.jooq.tools.LoggerListener#debug:255 - Executing query          : insert into "my_table" ("col1", "custom_column_array") values (?, ?::my_custom_type[]) returning "my_table"."col1"
DEBUG [main] org.jooq.tools.LoggerListener#debug:255 - -> with bind values      : insert into "my_table" ("col1", "custom_column_array") values ('My Col1', array[[UDT], [UDT]]) returning "my_table"."col1"

是我遗漏了一些配置还是一个错误？

干杯

正如相关问题 (https://github.com/jOOQ/jOOQ/issues/4162) 中所述，这是对此类 PostgreSQL 功能的缺失支持。到目前为止，问题中给出的答案是：

不幸的是，这是我们必须解决 PostgreSQL JDBC 驱动程序的几个限制的领域，它不实现 SQLData 和其他 API（另请参阅 pgjdbc/pgjdbc#63）。

目前，jOOQ 将数组和 UDT 绑定为字符串。似乎尚不支持此特定组合。您可能可以通过实现自己的自定义数据类型绑定来解决此限制：
