I have this password hash function that hashes a password to sha256. I've already got it running in pgadmin3 in a local database. I've done it by importing the extension, a feature that has been added a few versions ago.

To my schoolwork I need to run the trigger in a phppgadmin server but when I execute

CREATE EXTENSION pgcrypto; 

I get

ERROR:  could not open extension control file "/usr/share/postgresql/9.1/extension/pgcrypto.control": No such file or directory

How can I resolve this without having to change my hash to a weaker one (md5 or sha1)?

I'm assuming that you want to create this extension in another server. I'm guessing that the server didn't get the "postgresql contrib" package installed. This package contains the "standard" extensions that are available from the PostgreSQL source code.

I think you need to get the system administrator to install the required package for your OS.

For Debian and Ubuntu it's the "postgresql-contrib-9.1" package, for other platforms it has a similar name.

    You need to do sudo apt-get install postgresql-contrib-9.1 or it depends on the version of your postgres. – eloone Apr 14 '17 at 19:57
  • For Alpine Linux, apk add postgresql-contrib. – Arto Bendiken Jan 25 at 0:36
