Re: Unlinking Parallel Hash Join inner batch files sooner

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?
