Here is a backtrace with debug enabled:

I had a thought.  I remember configure checking for sfio (which I actually
have installed), but it wasn't checking for libstdio.a so I added
(AC_CHECK_LIB(stdio,     main)) to configure.in right under the sfio check
and ran autoconf then configure again.  This time I don't get a segfault.
It outputs the following:

test=# select current_user; current_user
--------------
 david
(1 row)

Then it doesn't echo what I type.  Without exiting, I typed select
current_user; again and it did output the following even though it didn't
echo what I was typing:
 current_user
--------------
 david
(1 row)

I tried a create table and as soon as I pressed enter, my key presses
stopped echoing.
