That's no

Attached is a fix replacing the flag with an array of flags, indexed by
ParallelMasterBackendId. Hopefully that makes it work

Hi,
While debugging something on 9.6, I've noticed that auto_explain handles
parallel queries in a slightly strange way - both the leader and all the
workers log their chunk of the query (i.e. the leader logs explain for
the whole query, while workers only log the parts they've been executing)
