> as part of HIVE-17721 we had changed the direct sql to acquire the lock for postgres as
> {code}
> select "NEXT_EVENT_ID" from "NOTIFICATION_SEQUENCE" for update;
> {code}
> however this breaks other databases and we have to use different sql statements for different databases
> for postgres use
> {code}
> select "NEXT_EVENT_ID" from "NOTIFICATION_SEQUENCE" for update;
> {code}
> for SQLServer
> {code}
> select "NEXT_EVENT_ID" from "NOTIFICATION_SEQUENCE"with (updlock);
> {code}
> for other databases
> {code}
> select NEXT_EVENT_ID from NOTIFICATION_SEQUENCE for update;
