fabtools.postgres.user_exists() quick fix

See original GitHub issue

For some reasons (gremlins ?) the test (res == "1") does not work even if the psql command returns "1" I found it worked better using ("1" in res), without any str.strip(), etc…

I use the root user to connect via SSH.

fab check_user
Executing task 'check_user'
res: 'could not change directory to "/root"\r\n1'
True

Done.

the check_user task is a call to pg_user_exists(username), it’s my modified function of postgres.user_exists(username)

def pg_user_exists(name):
    with settings(hide('running', 'stdout', 'stderr', 'warnings'),
        warn_only=True):
        res = _run_as_pg('''psql -t -A -c "SELECT count(*) FROM pg_user WHERE usename='%(name)s';"''' % locals())

    print "res: %r" % (res,)
    return '1' in res

def check_user():
    print pg_user_exists(DATABASE_OWNER)
