Ok. I did a manual patch and it Postgres 9.1.1 compiled for me without using the --disable-spinlocks option. Thanks a lot for the patch. :) By the way, could you please point me to the explanation on the significance of spinlocks for Postgres?

That patch should apply exactly to 9.1.0 or later. I think either you messed up copying the patch from the web page (note that patch is not forgiving about white space...) or else perhaps fooling with the file names messed it up. You shouldn't have to modify the file taken from the "patch" link at all. The right way to do it is to cd into the top source directory and use patch -p1 <patchfile which will tell patch how much of the filename to pay attention to (viz, not the "a/" or "b/" parts). If you get too frustrated, just wait till Monday and grab 9.1.3. regards, tom lane Larsen & Toubro Limited www.larsentoubro.com This Email may contain confidential or privileged information for the intended recipient (s) If you are not the intended recipient, please do not use or disseminate the information, notify the sender and delete it from your system. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
