PFA patch with minor improvements to documentation.

Also, what do you think about changing user-facing language from
"check checksum" to "verify checksum" ?  I see that commit ed308d78 actually
moved in the other direction, but I preferred "verify".

Commits

  1. Tweak wording of documentation for pg_checksums

  2. Add options to enable and disable checksums in pg_checksums
