I see different misbehavior (psql seems to lock up entirely, it doesn't slow down or eat CPU). But it's still misbehavior. "psql -n" doesn't have a problem, which says that this is probably a readline bug rather than our own bug. I think it's probably context dependent too; I'm pretty sure I've pasted big queries into psql without a problem while working directly on my work machine, but right now I'm ssh'd into it from a laptop and I do see a problem. [ further experimentation... ] A local psql on the laptop doesn't show a problem either. Both this and the one on the work machine are 8.1devel using readline-4.2a, so it doesn't seem to be an issue of different software versions. Maybe readline doesn't like ssh? [ still further experimentation... ] No, because ssh'ing to my *other* work machine and running psql there doesn't show a problem either. Curiouser and curiouser. But it's clearly very context dependent. You should probably tell us *exactly* what you are running, in every bit of software between you and psql. My tests here are with (local) Mac OS X 10.3.8, Apple-supplied X server and xterm terminal, Apple-supplied ssh (seems to be 3.6.1p1), local psql is current PG sources + readline 4.2a. The remote that doesn't work nicely is HPUX 10.20, sshd is openssh-3.7.1p2, current psql sources, readline 4.2a. The remote that does work nicely is Fedora Core 3, sshd 3.9p1-8.0.1, current psql sources, readline 4.3-13. I'm not seeing a pattern ... > Incidentally when I did that I only got back one row. What's up with that?
