Here's another version of 0002 after cleaning up almost everything from
David's review. I also added tests for ALTER STATISTICS in
sql/alter_generic.sql which made me realize there were three crasher bug
in here; fixed all those. It also made me realize that psql's \d was a
little bit too generous with dropped columns in a stats object. That
should all behave better now.
One thing I didn't do was change StatisticExtInfo to use a bitmapset
instead of int2vector. I think it's a good idea to do so.
I'll go rebase the followup patches now.
