psql and password

От

Hi,

I'm wondering how I can create a database for a user from within a script.
I have Pg in 'password' mode.
To create this database I'm trying to pass in the password from the script.
For example :

echo myPgPassword | /usr/local/pgslq/bin/createdb yourNewPgDatabase

But it's not working.
I'm still prompted for the password.

My goal is to create the database then change ownership of the database.
The user can then log straight in using phpPgAdmin.

Can you see where I'm going wrong ?
Any suggestions ?
Perhaps I need to use 'Expect' or something ( this is a Debian box )

Thanks
Kind Regards
Rudi.

Hi,

Thanks for the suggestions,

I ended up using Perl and DBI.
First I create a new database,
then create a new user,
then change owership of the database to the new user,
then create and entry for Apache's htpasswd facility.

Then the new user logs into the new database with there new htpasswd 
account via phpPgAdmin.
Thanks again.
For those interested here's my script.

Cheers
Rudi.

Script :
#!/usr/bin/perl -w

use DBI;

$DBH = DBI ->connect("dbi:Pg:dbname=oasis;host=moon","postgres","rudi2000");


foreach $_ (@ARGV)
{   # get name and pwd   @data = split(/:/,$_);   $thisname = $data[0];   $thispwd  = $data[1];     # create a new user
 $sql = $DBH->prepare("CREATE USER $thisname WITH PASSWORD '$thispwd' 
 
NOCREATEDB NOCREATEUSER;");   $sql->execute();
   # create a new database   $sql = $DBH->prepare("CREATE DATABASE $thisname WITH 
TEMPLATE=template0;");   $sql->execute();
   # change database ownership   $sql = $DBH->prepare("UPDATE pg_database SET datdba = (SELECT 
usesysid FROM pg_shadow WHERE usename = '$thisname') WHERE datname = 
'$thisname';");   $sql->execute();     # create htpaswd account   system("/usr/local/apache/bin/htpasswd -b
/home/realmz/phpPgAdmin
 
$thisname $thispwd >> /root/scripts/htpasswd_log.txt 2>&1");
}

$DBH->disconnect;

Set the environment variable:

PGPASSWORD=myPgPassword /usr/local/pgslq/bin/createdb yourNewPgDatabase
