pg_upgrade on Windows

Dear,



When one attempts to run pg_upgrade on Windows (7 SP 1 x64) the command
produces a failure notice, probably because writing to (log) files in
C:\Program Files and its subdirectories is not allowed.



C:\Program Files\PostgreSQL\9.5>pg_upgrade.exe --old-datadir "C:/Program
Files/P

ostgreSQL/9.4/data" --new-datadir "C:/Program Files/PostgreSQL/9.5/data"
--old-b

indir "C:/Program Files/PostgreSQL/9.4/bin" --new-bindir "C:/Program
Files/Postg

reSQL/9.5/bin"



cannot write to log file pg_upgrade_internal.log

Failure, exiting



Is there a way to redirect the log file to another file location?



Best regards,

Marc Daelemans
