Hibernet6 Enum type DDL issue

[frangere]

Env:

Spring Boot - 3.2.1
Hibernet  - 6.4.1
Mysql - 5.7
Liquibase : 4.25.1
Liquibase Hibernate6: 4.25.1

Gradle:

liquibase {
    activities {
        main {
            defaultsFile "liquibase.properties"
            changelogFile "base.mysql.sql"
            referenceUrl "hibernate:spring:com.xxx.model?dialect=org.hibernate.dialect.MySQLDialect"
        }
    }
}


dependencies {
    liquibaseRuntime 'com.mysql:mysql-connector-j'
    liquibaseRuntime 'org.liquibase:liquibase-core:4.25.1'
    liquibaseRuntime 'info.picocli:picocli:4.7.5'
    liquibaseRuntime 'org.yaml:snakeyaml:2.0'
    liquibaseRuntime 'org.liquibase.ext:liquibase-hibernate6:4.25.1'
    liquibaseRuntime 'org.springframework.boot:spring-boot-starter'
    liquibaseRuntime 'org.springframework.boot:spring-boot-starter-data-jpa'
    liquibaseRuntime sourceSets.main.output
}

Entity class:

public enum Status {
    ACTIVE,
    INACTIVE
}

@Entity
@Getter
@Table(name = "user")
public class User {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "id", nullable = false)
    private Long id;

    @Enumerated(EnumType.STRING)
    @Column(nullable = false)
    private Status status;
}

Try to use: gradle diffChangelog to generate sql file, got:

CREATE TABLE user (id BIGINT AUTO_INCREMENT NOT NULL,  status ENUM NOT NULL, CONSTRAINT userPK PRIMARY KEY (id));

which result in wrong SQL.

expected:

CREATE TABLE user (id BIGINT AUTO_INCREMENT NOT NULL,  status ENUM('ACTIVE', 'INACTIVE') NOT NULL, CONSTRAINT userPK PRIMARY KEY (id));

Root cause:
According https://docs.jboss.org/hibernate/orm/6.2/migration-guide/migration-guide.html#ddl-implicit-datatype-enum, Hibernate 6 uses enum types on MySQL by default, but Liquibase hibernate6 class ColumnSnapshotGenerator#toDataType cannot process hibernateType with ENUM('ACTIVE', 'INACTIVE'), this method just keep ENUM as sql type.

Workaround:
Right now, we are add:

   @JdbcTypeCode(SqlTypes.VARCHAR)
   private Status status;

to make sure still using old stype VARCHAR for ENUM.

In Postgres, there's a similar problem when we use an "Instant" column with Hibernate. Hibernate creates a type like timestamp(6) with time zone. But the toDataType function doesn't handle this properly and removes the time zone info, so it ends up as just timestamp(6).

Any updates on this?
This bug requires us to write all changelogs regarding enums manually.
