Intriguing indeed, to my understanding, after reading the blog post, it
looks like they're more interested in just switching rather than trying to
address the problem. Also,as someone mentioned on -general the post started
highly technical and promising, but slowly lost its focus.

For me looks like dead ahead they wanted to move (Maybe someone asked a
MySQL guy to do a PG thing, who knows...), but the issues are there... And
while it is a problem that can be addressed, it seems to be creating enough
FUD to make some people consider other options (MySQL was off the table a
month ago here... but is now being considered again due to this... but has
low chances of succeed hopefully lol)
