Hi,
I see in [1] that the reporter mentioned a delay between the error
message in parallel HashJoin and the return control back from PSQL. Your
patch might reduce this delay.
Also, I have the same complaint from users who processed gigabytes of
data in parallel HashJoin. Presumably, they also stuck into the unlink
of tons of temporary files. So, are you going to do something with this
code?
