About "ALTER USER" command

M�nica,

I need to change password of the usuary POSTGRES using the commando "ALTER
USER". This change I must do it by means of a program .bat in �quiet� way.

I have the following instruction in .bat program :

psql -S "ALTER USER postgres WITH PASSWORD 'xxtyod';"

But when I execute this program, it requests user password to me.

Sure. It's asking for the password of the user who will connect to the
database and issue the SQL command. There are several ways to avoid
this; the simplest is to create an appropiate .pgpass file (pgpass.conf
in Windows). The exact location is something like %APPDATA%/postgresql,
but better look it up in the documentation.

Alvaro:

In effect I published the file pgpass.conf and I added the following line:

localhost:5432:*:postgres:kklliu

However. I continued my instruction and follows without working to me.
Exists the way to invoke psql that is not of interactive way so that It
alters password of a user with no need to be in psql?

With the commando psql - S “ALTER USER…” it continues saying to me that that
data base does not exist, still modified the file pgpass.conf. If you know
some way in that this can be done, would be thankful to you immensely.

Sincerelly,

Well, if the message is that the database doesn't exist, you certainly
can't fix that by putting anything in pgpass.conf. I guess you should
be trying to connect to a database that does exist.

May I suggest you join the pgsql-es-ayuda list -- maybe you'll find it
easier to pose your questions in spanish instead. (They are quite
offtopic for pgsql-hackers anyway.) If you do, make sure you repost
your question with additional details, like a cut'n pasted extract of
psql going wrong, with the exact error message.
