In Postgres 9.2 we improved the logic of when generic plans are used by
EXECUTE. We weren't sure how well it would work, and the docs included
a vague description on when generic plans are chosen.
I have gotten a few questions lately about how prepared statements are
handled with multiple executions so I have updated the PREPARE manual
page with the attached patch to more clearly explain generic plans and
when they are chosen.
I would like to apply this to the 9.6 docs.
