pgsql: I noticed that the Partitioning section of the docs has *two*

Log Message:
-----------
I noticed that the Partitioning section of the docs has *two* sections
of caveats in different places, but close together. One called caveats,
one not. That looks like it just led to somebody not reading some
appropriate caveats in the second group of caveats (on -admin).
