      1. Create test_rank and test_rank_copy tables in PostgreSQL using the following script:

      create table test_rank(a integer);
create table test_rank_copy(expr1 integer);

      2. Add postgresql database configuration in standalone-teiid.xml:

      <datasource jndi-name="java:/test_pg" pool-name="test_pg" enabled="true" use-java-context="true">
                    <connection-url>jdbc:postgresql://localhost:5432/test?charSet=utf8</connection-url>
                    <driver-class>org.postgresql.Driver</driver-class>
                    <driver>org.postgresql</driver>
                    <pool>
                        <min-pool-size>2</min-pool-size>
                        <max-pool-size>70</max-pool-size>
                        <prefill>false</prefill>
                        <use-strict-min>false</use-strict-min>
                        <flush-strategy>FailingConnectionOnly</flush-strategy>
                    </pool>
                    <security>
                        <user-name>postgres</user-name>
                        <password>xxxxxx</password>
                    </security>
                    <validation>
                        <check-valid-connection-sql>select 0</check-valid-connection-sql>
                    </validation>
                    <timeout>
                        <blocking-timeout-millis>120000</blocking-timeout-millis>
                        <idle-timeout-minutes>5</idle-timeout-minutes>
                    </timeout>
                </datasource>

      3. Add in test-vdb.xml java:/test_pg configured in previous step as datasource:

      <model name="test_pg">
        <property name="importer.useFullSchemaName" value="false"/>
	<property name="importer.tableTypes" value="TABLE,VIEW"/>
	<property name="importer.importKeys" value="false"/>
        <source name="test_pg" translator-name="myPg" connection-jndi-name="java:/test_pg"/>
    </model>

      4. Configure in the test-vdb.xml the following virtual view:

      <model visible = "true" type = "VIRTUAL" name = "views">
        <metadata type = "DDL"><![CDATA[
          create view v as select rank() over (order by a) from test_pg.test_rank
        ]]>
        </metadata>
    </model>

      5. Run the following query:

      select * into test_pg.test_rank_copy from views.v ;;

      The error is caused by changes from TEIID-5153 issue, that is again the aggressive RuleCollapseSource.removeUnnecessaryInlineView method is guilty which removes all elements from requiredElements collection and calls RuleRaiseAccess.performRaise method which removes child node using NodeEditor.removeChildNode method. As a result in insert command we have not rewritten virtual view (view.v) which can't be resolved by PostgreSQL.
