Previous command not accessible in postgres 17 beta

Dear Concerned,
I wanted to let you know that I am running postgres 17 in rocky linux and
when I tries to fetch previous command by pressing up arrow key than
instead of fetching previous key, I am getting following values:
^[[A^[[A^[[B^[[A
Please look into this.

Thank You

Nothing around that has changed in Postgres. The likely cause is
either that your new psql was built without readline support, or
that you have the wrong TERM setting so that what your keyboard
emits for up-arrow is not what readline is expecting.

I had a new ubuntu install (JJ) and when I installed from source, I hit Readline error in with GCC.

I had to manually download libReadline-dev (or whatever it's exact name is)

not sure if it was mysetup, or Ubuntu or Source.

so if everything installed, Readline is probably OK.

I would look at Tom's second advice with TERM.

Hello,
Thank you for the response. It is solved now using readline library
