Running cb psql on version 3.4.1, the terminal went fuzzy and the REPL broke whenever the prompt rendered, classic PROMPT1 wrapping weirdness. I found that setting PROMPT1 to something simpler like \set PROMPT1 '(%n@%M:%>) %date +%H:%M:%S [%/] \n%x%# ' worked around it. The maintainer asked for the version and the reporter confirmed it was gone after updating to 3.5.1. Closed May 2024.
