Thread: Win32 Postgresql Command Line Password Specification

Win32 Postgresql Command Line Password Specification

From

Hi,
 
I have to run some command line commands that I have to run on a windows machine. Like pgsql, dropdb, createdb etc.
All these commands are runned from a php scripts.
 
Now, my question is how can I specify a User and Password to postgresql database system. I found out how can I say the user, but the password is always asked in the command line. I need this also to be specified in the command.
 
for example: dropdb database1 -U postgres -W.... always ask a password in the command line.
I want to specify in the command line the pass.
 
The only solution that I found for this problem is to put the postgre user autentication to trust and to skip the password.
 
Andy.

I think that's the best way to do it.
 
Rather than leave passwords lying around in script files, it might be best to trust a specific (specially created) user when running from a specific location on the specific database. Then you just have to keep that user account secure. I can imagine how it would work wth linux, but am not sure what problems youmay face under windows.
 
The only other alternative I can imagine is to use another program to type the password in automatically. I've never done it but I'm sure such a beast must exist.
 
The long and the short of it is (at least upto 7.4.6 - I don't know about later versions) thereis no way to specify the password on the commandline.
 
Regards
Iain

Not sure if it will work in windows, but in unix, I use the envrionmental variable PGPASSWORD

Not the safest thing in the world, but in my case, if a hacker's gotten through two layers of firewall, I'm sunk
anyhow.:)

The recommended method is to use the pgpass.conf file on Windows:

http://www.postgresql.org/docs/8.0/interactive/libpq-pgpass.html

There is also a PGPASSWORD environment variable, but this is
depreciated for security reasons.
