When the modified table is a partition table, the execution time of the ANALYZE command will increase as the number of partitions increases. When the ANALYZE statement is synchronized to the replica, it may cause replication lag.

Maybe make this feature a optional flag then? What do you think @timvaillancourt ?

@meiji163 considering this (I didn't think of it) I suggest this is an optional flag for now and we can have opt-in users report on performance

@wangzihuacool can you add an optional flag and doc/command-line-flags.md update for this one?
