Hi,

I reviewed and tested v2 of this patch.

Builds with zero errors and zero warnings and all tests passed.

Verified the fix against Bug #19393. The original crash (unique key violation on
pg_constraint_conrelid_contypid_conname_index)no longer occurs.
 
Also tested edge cases: cascading collisions (name, name1, name2 all taken), multiple NOT NULL columns with mixed
collisions,and the normal no-collision case. All work
 
correctly. No doc changes needed.

The new status of this patch is: Ready for Committer
