Haribabu Kommi, reviewed by Dilip Kumar and Rafia Sabih. Various cosmetic changes by me to explain why this appears to be safe but allowing inserts in parallel mode in general wouldn't be. Also, I removed the REFRESH MATERIALIZED VIEW case from Haribabu's patch, since I'm not convinced that case is OK, and hacked on the documentation somewhat.
