How to run shell script as postgres on remote server using fabric python

Question

How can I enter postgres sudo user to run a script in a specific folder? The reason I have to cd into the script is because it requires me to run it in that particular directory.

Would love inputs and comments on my approach and see if there is a better way.

The following is the fabric script I came up with. but it does't allow me to enter postgres user mode.

@task
def run():
    with sudo('-su postgres'):
        with cd('/home/XXX/www/my_app'):
            run('somescript.sh', use_sudo=True)

Thank you!

doc of sudo command

So you can switch user with sudo command like following:

sudo("mkdir /var/www/new_docroot", user="www-data")
