Re: Parallel safety tagging of extension functions

Another question which I thought of is what we should do with functions 
like pg_file_write() in adminpack.

While it is perfectly fine to modify files from the parallel workers, a 
user could get race conditions if he tries to modify the same file 
multiple times. Is this a kind of problem the PARALLEL tagging should 
try to prevent, or is that something we should leave to the user?
