It doesn't seem to work for me. I still have my ALTER TABLEs waiting:
\_ postgres: postgres cityvox [local] ALTER TABLE waiting
\_ postgres: autovacuum worker process   cityvox
\_ postgres: autovacuum worker process   cityvox
\_ postgres: autovacuum worker process   cityvox

I have a lot of NOTICE:  cancelling auto-analyze lines in my log but
it doesn't seem to change the overall behaviour (even if it's a bit
better than before). With cost delay of 20:
real    44m20.525s
user    0m35.757s
sys     0m2.985s
compared to 51 minutes before applying your patch.

The box is still idle for a long periods during the restore.
