One interesting thing is we can view the tables horizontally, without folding. we can use PAGER
environment variable. psql makes use of it. you can set
export PAGER='/usr/bin/less -S'
or just less -S
if its already availble in command line, if not with the proper location. -S to view unfolded lines. you can pass in any custom viewer or other options with it.
