I was just reading over the list of bugs fixed in 11.1 and encountered

This can be caused by adding local predicates explicitly, or by the
database generating them via transitive closure.

I have not seen the term "local predicate" before. Would I be right to
guess it means a predicate local to a subquery?
And am I also right to think that the transitive closure is generated
by the DBMS (?OPF) not the "database"? I don't see how it could come
from a database.
Yes, you would be right to think so.
I guess we all have our windmills. My recent favorite is trying to teach people
that DDR4 memory speeds, as in DDR4-3200, are in MT/s (million
transfers per second), not MHz. MHz are for clocks and DDR4-3200 runs
at 1600MHz - that's why it's Double Data Rate. Even the memory
manufacturers mis-label their own product.
I'll forward your complaint to, uh, the proper people. :-)
