Another thing that could be helpful is if you "set trace_sort = on"
within your session/pgAdmin, and showed us log output from the start of the failing CREATE INDEX to the point that it fails. You may or may not want to "set client_min_messages = LOG" while you're at it, since that will send LOG output to the client, which may be more convenient.
