Command-line client sometimes misinterprets tabs for nulls
Let's say I have typed a nice formatted SQL statement like so:
select b1.blah,
b1.blah2,
b2.blah3
from blah_table as b1
inner join only blah_table2 as b2
on b1.blah = b2.blah;
...using tabs as the indenting medium. Now I copy that from my editor into
psql, and most of the tabs are converted to nulls, resulting in an error like
"Unknown value fromblah_table". Tabs should paste; they're normal
characters.

The problem is that most items in postgresql are tab completed.
Cut and past your text into a bash or zsh prompt. It injects a bunch of
filenames into your data, as per tab completion.
Annoying, but for the benefits it's livable.
Perhaps a toggle could be created to disable tab completion?

TIP 2: you can get off all lists at once with the unregister command
(send "unregister YourEmailAddressHere" to majordomo@postgresql.org)

Turn off readline (psql -n). For someone accustomed to tab completion,
the above is about as sensible as demanding we disable backspace.
It would be nice if we could distinguish pasted tabs from manually-typed
tabs, but I'm not aware of any way that psql could tell the difference.

Right, my original build of postgres did not have tab completion support as I
did not have readline (a notice at the end of the configure script would have
been nice, maybe a summary of what will and won't be supported?). However, I
love the command-line history, so readline was a must ;).

tabs, but I'm not aware of any way that psql could tell the difference.
Can tab completion be disabled without disabling command line history? I
noticed -n disables both. I would gladly trade tab completion for tab
pastability, but I rely heavily on command line history.
Thanks,

Get out the readline man page. I believe you can configure it six
ways from Sunday, but I've never tried myself ...

Perhaps annoying, but a simple work around is to use
<space><tab><space><tab>
Formats like tab in the code, but space/tab combinations don't complete
to anything, registering like a space in psql.

man psql, search for "disable"
Also, you might find it easier to start an editor using \e and paste your
code there.
