[Nix-dev] Unstable channel is still stuck (was: Unstable channel stuck?)

[Peter Simons]

Now we have a new error message:

  DBIx::Class::Storage::DBI::_dbh_execute(): DBI Exception: DBD::Pg::st execute failed: ERROR:  deadlock detected
  DETAIL:  Process 42952 waits for ExclusiveLock on tuple (2,29) of relation 16540 of database 16386; blocked by process 8211.

I don't think anyone but the system administrator of the machine can do
anything about this one. :-(
