What change(in Postgres?) makes it possible to remove the flag?

We can delete the same parameters in HiveConf and some test cases as well.

With the help of HIVE-26976, it's possible to recover from the direct sql by rolling back to the savepoint before sql execution,

Makes sense for me if we update the three files. The test error looks related.

Done, looks the latest failure isn't related

@dengzhhu653 , HiveConf changes in this PR are big +1 , I need some input on how to deal with the deprecated Metastore configs present in HiveConf. For example:

METASTORE_AGGREGATE_STATS_CACHE_MAX_FULL
METASTORE_AGGREGATE_STATS_CACHE_CLEAN_UNTIL
...

I had filed HIVE-29289 and the goal was to remove these configurations from HiveConf. Mostly these configs are used in test code. I was thinking of moving those tests in itests module to prevent cyclic depenedency if caused by adding metastore-comomon as dependency. Can you provide your thoughts on this?

Not sure how it could introduce the cyclic depenedency, the hive-common has already contained the dependency on metastore-common, can you give an example?
