I have a postgresql database 9.3.4 installed on a qnap nas. I would like to change the postgres password but I can not. I log in with phpPgAdmin and, in a sql window, I write:
ALTER USER postgres PASSWORD 'mynewpassword'
The query is executed correctly but the password does not change, even after restarting the nas. What could be the problem? The same operation I did on my pc windows and it worked fine.
