I'm working on a tool that runs pg_restore with -j 4. I notice that
after COPYing in the data, pg_restore does two indexes and a cluster
command in parallel. The first CREATE INDEX is running, the CLUSTER
command is waiting on it and the second CREATE INDEX is waiting on the
CLUSTER. This seems sub-optimal. Would it make sense to run the
CLUSTER command first? I'm pretty sure I can replicate the behavior if
necessary. Running 9.1.2.
