During recent developments in the vacuum, it has been noticed [1] that
parallel vacuum workers don't use any buffer access strategy. I think
we can fix it either by propagating the required information from the
leader or just get the access strategy in each worker separately. The
patches for both approaches for PG-13 are attached.
Thoughts?
