Oracle 与Postgres分离，不替换changelog参数

我将liquibase与oracle和postgres一起使用，我想使用changeLog属性来定制两个数据库中不同的变更集元素

我使用的例子来自

这是我的db-changelog.xml

<databaseChangeLog
        xmlns="http://www.liquibase.org/xml/ns/dbchangelog"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns:ext="http://www.liquibase.org/xml/ns/dbchangelog-ext"
        xsi:schemaLocation="http://www.liquibase.org/xml/ns/dbchangelog http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-2.0.xsd
        http://www.liquibase.org/xml/ns/dbchangelog-ext http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-ext.xsd">

    <property name="table.name" value="table_O" dbms="oracle"/>
    <property name="table.name" value="table_P" dbms="postgres"/>

    <property name="column1.name" value="column1_O" dbms="oracle"/>
    <property name="column1.name" value="column1_P" dbms="postgres"/>

    <property name="column2.name" value="column2_O" dbms="oracle"/>
    <property name="column2.name" value="column2_P" dbms="postgres"/>

    <property name="clob.type" value="blob" dbms="oracle"/>
    <property name="clob.type" value="bytea" dbms="postgres"/>

    <changeSet id="1" author="joe">
         <createTable tableName="${table.name}">
             <column name="id" type="int"/>
             <column name="${column1.name}" type="${clob.type}"/>
             <column name="${column2.name}" type="int"/>
         </createTable>
    </changeSet>
</databaseChangeLog>

工作正常，我获得了oracle的changelog，但是命令

$ liquibase --driver=oracle.jdbc.OracleDriver \
            --classpath=ojdbc8-18.3.0.0.jar \
            --changeLogFile=db.changelog.test.xml \
            --url=jdbc:oracle:thin:@localhost:1521/my_db \
            --username=my_user \
            --password=my_pwd \
            --logLevel debug updateSQL > simple_changeLog_ORACLE.sql

$ liquibase --driver=org.postgresql.Driver \
            --classpath=postgresql-42.2.5.jar \
            --changeLogFile=db.changelog.test.xml \
            --url=jdbc:postgresql://localhost:15432/my_db \
            --username=my_user \
            --password=my_pwd \
            --logLevel debug updateSQL > simple_changeLog_POSTGRES.sql

失败，出现以下异常

选项--logleveldebug显示解析的变更集中的差异

甲骨文是

17:59:43.184 DEBUG [liquibase.util.MD5Util]: Computed checksum for createTable:[
    columns=[
        [
            name="id"
            type="int"
        ],
        [
            name="column1_O"
            type="blob"
        ],
        [
            name="column2_O"
            type="int"
        ]
    ]
    tableName="table_O"
] as 836321c599b350ca366cc6ea3bde3890

而博士后是

        [
            name="id"

            name="${column1.name}"
            type="${clob.type}"
        ],
        [
            name="${column2.name}"
            type="int"
        ]
    ]
    tableName="${table.name}"
] as 71476a8361010689730a8bf91f8d7115

我遗漏了什么吗？

我认为唯一的问题是postgres使用的值是

postgresql

，而不仅仅是

postgres
