我尝试获取其中包含nasted查尔兹的记录，但得到PSQLException语法错误和org.jooq.exception.DataAccessException。

record ChildRecord(Integer parentId) {}
        record ParentRecord(Integer parentId, List<ChildRecords> childs) {};

        List<ParentRecord> parents dsl.select(ParentTable.ID,
                        multiset(
                                select(ChildTable.ID)
                                        .from(ChildTable)
                                        .where(Parent.ID
                                                .eq(Child.PARENT_ID)))

                                .as("childs")
                                .convertFrom(records -> records.map(Records.mapping(ChildRecord::new))))
                .from(ParentTable)
                .fetchInto(ParentRecord.class);
        return parents;
    }

要注意使用Java记录与非常有限的信息选择只是为了使这一工作。但获取stacktrase：

使用JOOQ 18.0 Postgres 14.5 Spring Boot v2.7.8、Springv5.3.25 Java 17.0.5
我在这个问题上哪里错了？

postgresql

堆栈跟踪的关键行如下：

at org.jooq_3.18.0.DEFAULT.debug(Unknown Source) ~[na:na]

SQLDialect.DEFAULT用于呈现SQL，而不是SQLDialect.POSTGRES，后者应该用于在PostgreSQL上运行查询。
