SQL
#postgre分区 create table if not exists ip_count_20200302 partition of ip_count for values from (20200302) to (20200303);
可能问题:
从druid的issue来看，druid的merge不支持postgresql的 partition字段
解决办法
1.关闭mergeSQL功能
#springboot spring.datasource.druid.filter.stat.merge-sql=false
2.忽略该error虽然报error.但是语句是可以执行成功的，请自行校验
