liquibase 无法在分区 table 上创建索引和唯一约束

Question

Liquibase 文件如下:

数据库变更日志：

  - changeSet:
      id: 1
      author: roran
      changes:
        - createTable:
            tableName: account_balance
            columns:
              - column:
                  name: id
                  type: bigint
                  autoIncrement: true
                  constraints:
                    primaryKey: true
              - column:
                  name: account_id
                  type: bigint
                  constraints:
                    nullable: false
              - column:
                  name: balance_date
                  type: date
                  constraints:
                    primaryKey: true
              - column:
                  name: create_date
                  type: timestamptz
              - column:
                  name: created_by
                  type: varchar(100)
              - column:
                  name: update_date
                  type: timestamptz
              - column:
                  name: updated_by
                  type: varchar(100)
        - modifySql:
            applyToRollback: false
            dbms: postgresql
            append:
              value: PARTITION BY RANGE (balance_date);
        - addUniqueConstraint:
            columnNames:  balance_date, account_id
            tableName:  account_balance
        - createIndex:
            columns:
              - column:
                  name:  account_id
            indexName:  account_id_idx
            tableName:  account_balance

我在启动 spring 引导应用程序时添加唯一约束时遇到以下错误

Migration failed for change set /db/changelog/changes/1.create-account-balance-table.yml::1::roran: Reason: liquibase.exception.DatabaseException: ERROR: syntax error at or near PARTITION Position: 93 [Failed SQL: (0) ALTER TABLE public.account_balance ADD UNIQUE (balance_date, account_id)PARTITION BY RANGE (balance_date);]\tat org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1794)\tat org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.doCreateBean(AbstractAutowireCapableBeanFactory.java:594)\tat org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.createBean(AbstractAutowireCapableBeanFactory.java:516)\

同样，我在启动 spring 引导应用程序时添加索引时遇到错误。

liquibase.exception.MigrationFailedException: Migration failed for change set db/changelog/changes/1.create-account-balance-table.yml::1::roran: Reason: liquibase.exception.DatabaseException: ERROR: syntax error at or near PARTITION Position: [Failed SQL: (0) CREATE INDEX account_id_idx ON public.account_balance_p0(account_id)PARTITION BY RANGE (balance_date); CREATE TABLE public.account_balance_p0 PARTITION OF account_balance FOR VALUES FROM ('2020-10-01 00:00:00') TO ('2020-11-01 00:00:00');]\tat liquibase.changelog.ChangeSet.execute(ChangeSet.java:646)\tat liquibase.changelog.visitor.UpdateVisitor.visit(UpdateVisitor.java:53)\tat liquibase.changelog.ChangeLogIterator.run(ChangeLogIterator.java:83)\tat liquibase.Liquibase.update(Liquibase.java:202)\tat

同样工作正常，如果我通过 liquibase 创建 table，然后通过编程方式创建索引或添加约束，如下所示

CREATE INDEX account_id_idx ON public.account_balance(account_id);

我在 liquibase 中为分区 table 使用 yaml 的方式有什么错误吗？

我正在使用 postgresql 11 版本和 liquibase spring boot 2.3.3.RELEASE

您的 ChangeSet 的 modifySql 类型也适用于您的 addUniqueConstraint 和 createIndex 类型。由于在 Index 和 UniqueConstraint 创建中添加了 PARTITION BY RANGE，因此生成的 sql 出现异常。

只需将它分成两部分 - 一个包含 table 创建的 ChangeSet 和一个包含 Index 和 UniqueConstraint 创建的 ChangeSet：

  - changeSet:
      id: 1
      author: roran
      changes:
        - createTable:
            tableName: account_balance
            columns:
              ...
        - modifySql:
            applyToRollback: false
            dbms: postgresql
            append:
              value: PARTITION BY RANGE (balance_date);

和

  - changeSet:
      id: 2
      author: roran
      changes:
        - addUniqueConstraint:
            columnNames:  balance_date, account_id
            tableName:  account_balance
        - createIndex:
            columns:
              column:
                name:  account_id
            indexName:  account_id_idx
            tableName:  account_balance
