What's the use case for this?
It's not compatibility, is it? Why would you ever do that? If you did,
why would you expect it to work? Seems more likely to be a user error
than a real request.
Should it throw one trigger call, or two?
BTW, create index foo_idx on foo (col1, col1) fails also with a strange
error message. Should we silently merge columns and ignore that also?
ERROR: duplicate key value violates unique constraint
"pg_attribute_relid_attnam_index"
Seems easier to throw errors for weird DDL like this.
e.g. create index concurrently on foo (col1); creates an index called
"concurrently" on foo, while holding locks...
