Hi,
The 9.2.3 release notes say:
* Fix pg_upgrade's -O/-o options (Bruce Momjian)
You got it the wrong way around, he was the one who introduced the bug! ;)
I originally found, debugged and provided the fix:
http://www.postgresql.org/message-id/CABRT9RBy1uRTMY-DfLDgBPCp+ZQU36M_+BLD4WFWuGOhg-M4hw@mail.gmail.com
No big deal, it was just one space, but I wanted to voice my
disagreement with how Postgres committers don't retain original patch
authorship information.
Regards,
Marti
