Druid 配置了SQL合并后，在查询PostgreSQL 主键ID是报错?报错

@wenshao 你好，想跟你请教个问题：

连接池配置

<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
		destroy-method="close">
		<property name="driverClassName" value="${jdbc.driverClassName}" />
		<property name="url" value="${jdbc.url}" />
		<property name="username" value="${jdbc.username}" />
		<property name="password" value="${jdbc.password}" />

		<property name="filters" value="stat" />
	        <property name="connectionProperties" value="druid.stat.mergeSql=true"/>

                <property name="maxActive" value="20" />
		<property name="initialSize" value="1" />
		<property name="maxWait" value="60000" />
		<property name="minIdle" value="1" />

		<property name="timeBetweenEvictionRunsMillis" value="3000" />
		<property name="minEvictableIdleTimeMillis" value="300000" />

		<property name="validationQuery" value="SELECT 'x'" />
		<property name="testWhileIdle" value="true" />
		<property name="testOnBorrow" value="false" />
		<property name="testOnReturn" value="false" />

		<property name="poolPreparedStatements" value="true" />
		<property name="maxPoolPreparedStatementPerConnectionSize" value="20" />

	</bean>

这条的话，就会报这个错
