Re: How To Install Extension Via Script File?

Hi all,

I have a database that uses the ltree extension.  I typically create a new database like so (as a normal user), using my script file:

CREATE DATABASE mydb WITH TEMPLATE template0 ENCODING 'UTF8';

And then su to postgres, login and install the ltree extension on mydb.  Then I logout of my psql instance and re-run the script (as a normal user) to create the tables & views on mydb.  I comment out the table/view creation portion until I finish the first couple steps, and then uncomment the tables and views on the 2nd run.  Otherwise the script will fail because the ltree extension has to be installed as a superuser.

I want a script something like:

CREATE DATABASE mydb WITH TEMPLATE template0 ENCODING 'UTF8';

\c mydb

CREATE EXTENSION ltree;

CREATE TABLE mytable(myfields);

rinse, repeat for additional tables and views.

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.

I did create a password for my postgres user (hence the -W option).  And this is on a local box.

How can I run my script?

Thanks!

Don
