Thread: BUG #15748: arrow keys doesn't work

The following bug has been logged on the website:

Bug reference:      15748
Logged by:          Biruk Takele
Email address:      biruktakele24@gmail.com
PostgreSQL version: 10.3
Operating system:   linux
Description:

the arrow keys write like this ^[[A, ^[[B, ^[[C, ^[[D The commands history
"is not working": meaning I cannot retrieve these
last commands I entered by hitting the top arrow key.
Instead, I have to type them again.
it happens on Linux PostgreSQL shell.
can you solve me this problem?

Which Linux exactly? How did you install PostgreSQL?

Usually this just means that the $TERM variable in your shell doesn't
match the terminal you are really using.
