Correct CREATE INDEX documentation for opclass parameters

akorotkov · akorotkov · commit 3eabc62312ef · 2020-04-01T15:01:26.000+03:00
Old versions of opclass parameters patch supported ability to specify DEFAULT as the opclass name in CREATE INDEX command. This ability was removed in the final version, but 911e702 still mentions that in the documentation.
