And to be able to run it from the Bash prompt (as securely as possible).

I thought I could add the commands and run the create script by doing:
sudo -u postgres psql -U user -W -d mydb --file=/home/user/dev/mydb_create.sql

I thought that, running my script as the superuser, it would have the privileges necessary
to install the extension, but I still got a "permission denied" error.

You are not running the script as superuser because you supplied "-U user" and thus the _script_ is executed
as "user". psql is started as "postgres" (the Linux user, not the DB user).

My bad - forgot to change the example above to reflect accurately the user...  I did use the postgres user.
 

I don't see the reason for using sudo in the first place, -U is enough:

Fair enough.  But I think you are onto something here below...

Leave out the sudo, and use:

  psql -U postgres -W -d mydb --file=/home/user/dev/mydb_create.sql

Or if you do want to use sudo, the leave out the -U user parameter:

  sudo -u postgres psql -d mydb --file=/home/user/dev/mydb_create.sql

When I try a simple psql -U postgres -W - just to initiate the psql session, I get:
psql: FATAL:  Peer authentication failed for user "postgres"
 

It's like my regular user cannot connect as the postgres user.

However, this works (with me just typing my password for sudo):
donp@wiesbaden:~$ sudo -u postgres psql -U postgres
[sudo] password for donp:
psql (9.1.9)
Type "help" for help.

postgres=# \q

Maybe I have some permissions issues?

Thanks,
Don
