Cannot start app after update with Erlang 24

After updating with Erlang 24 I cannot start app because the function :pg2.create/1 is undefined or private. Here is the response I get after executing mix phx.server

** (Mix) Could not start application wui: Wui.Application.start(:normal, ) returned an error: shutdown: failed to start child: Wui.Endpoint
** (EXIT) shutdown: failed to start child: Phoenix.PubSub.PG2
** (EXIT) shutdown: failed to start child: Phoenix.PubSub.PG2Server
** (EXIT) an exception was raised:
** (UndefinedFunctionError) function :pg2.create/1 is undefined or private
(kernel 8.0) :pg2.create({:phx, Wui.PubSub})

(stdlib 3.15) gen_server.erl:390: :gen_server.init_it/6
(stdlib 3.15) proc_lib.erl:226: :proc_lib.init_p_do_apply/3

Any advice on how to proceed will be much appreciated. Thanks in advance.
