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/...
