No, and while people used to, we're past that now.

However, infrastructure improvements to make out-of-tree logical
replication that we can get into user hands *now* rather than two+ years
from now have been getting knocked back because there's no in-tree user,
and tools like pglogical dismissed as irrelevant. Once we have logical
replication in core hopefully we can start making infrastructure progress
again as well.
