I think I can explain this one. In the refactoring patch that Joachim
submitted and I committed, the struct was called _parallel_state, using
the same naming convention with the useless _ suffix and all lowercase
that already plagued the pg_dump code. This name is pointlessly
different from the typedef -- maybe the original pg_dump author thought
the names would collide and chose them different. But this is not true,
looks ugly to me, and furthermore it is inconsistent with what we do in
the rest of the PG code which is to use struct names identical to the
typedef names. So I changed it -- without realizing that the subsequent
patch would move the declarations elsewhere, losing my renaming.
