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.

            regards, tom lane

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.
