choose an index name the same as it would do for an unnamed index constraint. (My recent changes to the index naming logic have helped to ensure that this will be a reasonable choice.) Per a suggestion from Peter. A necessary side-effect is to promote CONCURRENTLY to type_func_name_keyword status, ie, it can't be a table/column/index name anymore unless quoted. This is not all bad, since we have heard more than once of people typing CREATE INDEX CONCURRENTLY ON foo (...) and getting a normal index build of an index named "concurrently", which was not what they wanted. Now this syntax will result in a concurrent build of an index with system-chosen name; which they can rename afterwards if they want something else.
