After upgrade from 9.1 to 9.3, commands still point to 9.1

Upgraded from 9.1 to 9.3 on my Ubuntu 12.04 server. Everything worked great but running commands like ‘createdb’ still runs them from the 9.1 path.

/usr/lib/postgresql/9.1/bin/createdb: unrecognized option....

Edit, additional info:
I used this gist https://gist.github.com/ibussieres/11262268
I already uninstalled 9.1 with the regular ‘sudo apt-get remove postgresql-9.1′

This is the output of requested commands

which createdb
  /usr/bin/createdb

createdb --version
  createdb (PostgreSQL) 9.1.14

which psql
  /usr/bin/psql

psql --version
  psql (PostgreSQL) 9.3.5
