seems to me that Ubuntu is using readline (but I might be wrong)

from /usr/bin/psql:

# libreadline is a lot better than libedit, so prefer that
if ($cmdname eq 'psql') {   my @readlines;   push @readlines, sort(</lib/libreadline.so.*>);   if (@readlines) {
$ENV{'LD_PRELOAD'}= ($ENV{'LD_PRELOAD'} or '') . ':' . $readlines[-1];   } 
}

also, LD_PRELOAD is not referenced anywhere in /etc/postgrest/...
