Hello hackers!
I am an Oracle/PostgreSQL DBA, I am not a PG hacker. During my daily job, I find a pain that should be fixed.
As you know, we can use the UP arrow key to get the previous command to avoid extra typing. This is a wonderful feature to save the lives of every DBA. However, if I type the commands like this sequence: A, B, B, B, B, B, B, as you can see, B is the last command I execute.
But if I try to get command A, I have to press the UP key 7 times. I think the best way is: when you press the UP key, plsql should show the command that is different from the previous command, so the recall sequence should be B -> A, not B -> B -> ... -> A. Then I only press the UP key 2 times to get command A.
I think this should change little code in psql, but it will make all DBA's lives much easier. This is a strong requirement from the real DBA. Hope to get some feedback on this.
