Re: psql: Buggy interactions with wraparound in maximized gnome terminal

Ok, makes sense. Since psql depends on readline, I'm adding their bug
mailing list to the loop, and reposting the original bug report:

This is probably hard to reproduce, but I entered a state where the
command I was writing was wrapping around at the 81st character while
in full screen,  and the 1st character was being overwritten.This did
not affect the command sent to the server, but I would not have a way
to see what command I just entered.

I'm using ubuntu 18.04, the terminal is Gnome Terminal 3.28.2

Below is a short video showcasing the issue.  I thought I had muted my
mic, but apparently I didn't, please enjoy my nation's anthem while
observing said bug.

Additionally, while researching this bug, I found a reproducible
variation of this bug:

1- Open a terminal at a normal size.
2- Write enough characters so that they correctly wrap around into a new line.
3- Maximize the window
4- Minimize it again

You will find that the command is visibly duplicated. Again this is
aesthetic, the command is not duplicated when it's sent to the server.
You can find a video of this bug below  (I gotta learn how to turn
that mic off)

Good luck! Let me know if you need any help.
