My 2 tables use different field names.. So table1 has a field identitygroupname, pointing to another table, properly mapped with a table relationship. table2 has a field identitygroups, pointing to another table, properly mapped with a table relationship.

my $foo = $t1->identitygroupname->name;
my $bar = $t2->identitygroup->name;

The belongs_to definition in DBIC::Schema::Result::T1 looks like this:

__PACKAGE__->belongs_to(
  "fieldwith",
  "DBIC::Schema::Result::R1",
  { id => "fieldwiths" },
  {
    is_deferrable => 0,
    join_type     => "LEFT",
    on_delete     => "NO ACTION",
    on_update     => "NO ACTION",
  },
);

I'm not sure if this is a bug in dbicdump or something on purpose. I very much doubt that this is a Postgresql issue.
