Type "help" for help.
Now I copy/paste your select line:
db=# select '';
?column?
----------
(1 row)
The ä just never appears.
I press "up arrow", then "left arrow" twice then "Das Mdchen geht
raus.", then left arrow to go between the "M" and the "d":
db=# select 'Das Mdchen geht raus.';
^
(The "^" indicates the position of the cursor.)
So far, so good. Now I type "ä", I get:
db=# select 'Das MDchen geht raus.';
^
The "d" was capitalised and the cursor moves forward until the next
blank or punctuation, instead of "ä" appearing. Similar results with
é, è, ñ. Typing ° or ♥ causes the cursor to go backwards until
beginning of word. Typing ß transforms Mdchen into MDchenMDchen (with
cursor at the end of that word).
You seem to use a version of the package that is not in Debian. Are
you sure it is linked against libedit? I'm asking because you probably
compiled postgresql-9.0 (a version of the package you intend to upload
to Debian at some future date, maybe?) on your machine yourself, maybe
not in a clean-minimal chroot, and then maybe you had *both*
libedit-dev *and* libreadline-dev installed and the ./configure call
picked readline. That's a bug in itself, actually. Results of
compilation should not depend on what extra thing is or is not
installed, as long as no build-conflicts is declared. I suggest you
add "--with-libedit-preferred" to the ./configure call. (Declaring a
Build-Conflicts would fix that second bug, too, but it is less
convenient for developers and users wishing to recompile
postgresql-9.0.)
