从oracle迁移到postgres - PostgreSQL上的JPA迁移错误

我们正在从Oracle迁移到PostgreSQL。我们的Web应用程序服务器是WebSphere，我们也使用JPA来管理持久性。

在我将所有SQL查询转换为与PostgreSQL语法对齐之后，我启动了服务器并得到了一个奇怪的异常。我试图转换Oracle数据表创建的每一行，它应该使用从smallint of Oracle的boolean到PostgreSQL上的Boolean：

特定列的类型为布尔值。

SELECT * FROM VariableEntity v是正在执行的查询。实体定义如下：

@Id
private int pk;

@Version
private int version;

@Column(length = FieldLengths.MAX_NAME_LENGTH_IN_DB)
private String name;

@Column(nullable = false)
private int dataTypeId;

@Column(nullable = false)
private boolean archived;

@Temporal(TemporalType.TIMESTAMP)
private Date creationTime;

@Column(name = "COMMENT1", length = FieldLengths.MAX_COMMENT_LENGTH_IN_DB)
private String comment;`

Column | Type | Modifiers | Storag e | Stats target | Description ---------------------------+--------------------------------+-----------+------- ---+--------------+------------- pk | integer | not null | plain | | name | character varying(128) | | extend ed | | datatypeid | integer | not null | plain | | archived | boolean | not null | plain | | comment1 | character varying(3000) | | extend ed | | creationtime | timestamp(0) without time zone | | plain | | behaviorintimetemplate_pk | integer | | plain | | version | integer | | plain | | Indexes: "pk_variable1" PRIMARY KEY, btree (pk)

这是我打开JPA的Websphere日志后的JPA跟踪：
