Add postmaster/postgres undocumented -b option for binary upgrades.

Browse Source 
This option turns off autovacuum, prevents non-super-user connections,
and enables oid setting hooks in the backend.  The code continues to use
the old autoavacuum disable settings for servers with earlier catalog
versions.

This includes a catalog version bump to identify servers that support
the -b option.
