SQL access to access method details

While working on a tool to capture catalog/stats info and looking at 
cross version compatibility, I noticed that the pg_am changes removed 
SQL access to a bunch of AM info. [1] indicates that's part of the 
purpose of the patch; are we sure no tools are using this info? Unlike 
previous catalog compatibility breaks, this one completely removes that 
information, so if someone was using it they're now completely hosed.
