The changes here make it impossible to write a bgworker which properly
works in 9.3 and 9.4. Was that intended? If so, the commit message
should mention the compatibility break...

That causes warnings like:
/home/andres/src/postgresql/contrib/bdr/bdr.c:655:24: warning: assignment from incompatible pointer type [enabled by default]
apply_worker.bgw_main = bdr_apply_main;
^
/home/andres/src/postgresql/contrib/bdr/bdr.c:744:25: error: incompatible types when assigning to type ‘char[64]’ from type ‘char *’
apply_worker.bgw_name = fullname;

And the bgw_name change will probably actually cause crashes...

If it was intended I propose changing the signature for 9.3 as
well. There's just no point in releasing 9.3 when we already know which
trivial but breaking change will be required for 9.4
