Alvaro Herrera b2603f16ad Document concurrent indexes waiting on each other ... Because regular CREATE INDEX commands are independent, and there's no logical data dependency, it's not immediately obvious that transactions held by concurrent index builds on one table will block the second phase of concurrent index creation on an unrelated table, so document this caveat. Backpatch this all the way back. In branch master, mention that only some indexes are involved.
