pg_trigger's index on tgrelid is replaced by a unique index on
(tgrelid, tgname). This provides an additional check on trigger name
uniqueness per-table (which was already enforced by the code anyway).
With this change, RelationBuildTriggers will read the triggers in
order by tgname, since it's scanning using this index. Since a
predictable trigger ordering has been requested for some time, document
this behavior as a feature. Also document that rules fire in name
order, since yesterday's changes to pg_rewrite indexing cause that too.
