Here’s what I get when I do "otool -L /usr/local/bin/psql";

/usr/local/bin/psql:
/usr/local/lib/libpq.5.dylib (compatibility version 5.0.0, current version 5.13.0)
/usr/local/opt/readline/lib/libreadline.8.dylib (compatibility version 8.0.0, current version 8.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1292.0.0)

Right, so that's using a version of libreadline that's supplied by
Homebrew (the /usr/local/opt path is the giveaway on that).
I don't know whether these things represent an intentional change
of libreadline's behavior in Homebrew's build, or a bug, but in
either case you should take the issue to the Homebrew support forums.
If it's intentional, I imagine there's a way to get the old behavior
back.
Also, libreadline is fairly configurable, so maybe this boils down
to some unintentional change in your ~/.inputrc ?

“microscopic” explanation. I’ll have to to a fair bit of research to find out what to do to fix this problem.

I would start here:

https://www.google.com/url?q=https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/postgresql.rb&source=gmail-imap&ust=1613508580000000&usg=AOvVaw2xLlZxQZO_RhB3g_4CE9Ol

and contact the maintainer:

FYI, the formula points at another formula for readline:

def install
   ENV.prepend "LDFLAGS", "-L#{Formula["openssl@1.1"].opt_lib} -L#{Formula["readline"].opt_lib}"
   ENV.prepend "CPPFLAGS", "-I#{Formula["openssl@1.1"].opt_include} -I#{Formula["readline"].opt_include}"

which can be found here:
