Subject: [PATCH v1 2/2] Doc: GiST inet_ops is now the default opclass for inet
 and cidr.

Commit b352d3d80 marked the built-in GiST inet_ops opclass as
opcdefault, but missed the paragraph in gist.sgml that says it is not
the default for inet and cidr and tells users to name it explicitly
in CREATE INDEX.  Say that it is the default as of v19, and point to
btree_gist's documentation for why it wasn't before and what that
means for upgrades.

Back-patch to v19.
