nixos/keycloak: database isn't locally created when host set to a unix path

[VlaDexa]

Nixpkgs version

• Unstable (26.05)

Describe the bug

this doesn't account for instances when database is local and host is a unix socket

nixpkgs/nixos/modules/services/web-apps/keycloak.nix

Line 441 in ffbc9f8

databaseActuallyCreateLocally = cfg.database.createLocally && cfg.database.host == "localhost";

Steps to reproduce

  services.keycloak = {
    enable = true;
    database.host = "/run/postgresql";
    plugins = with pkgs.keycloak.plugins; [
      junixsocket-common
      junixsocket-native-common
    ];
  ...
  };

Expected behaviour

for database to be created even if host is a unix socket
