Hi Tom,
I tried to apply the patch. I succeeded in patching configure, configure.in and
src/include/pg_config.h.in files.
But while applying the patch for src/include/storage/s_lock.h , I am getting an
error.
This is how I am doing the patch,
1. I copied the diff output given in the link mentioned in the below email.
2. Changed the file names appropriately (patch file path is different from
source file path. But I have initialized --- and +++ appropriately
3. Executed the patch command in the Postgres 9.1.1 directory as "patch
src/include/storage/s_lock.h -i s_lock.h_Patch"
4. Got the following output
Hunk #1 succeeded at 252 with fuzz 1.
Hunk #2 FAILED at 292.
1 out of 2 hunks FAILED -- saving rejects to file
src/include/storage/s_lock.h.rej
Thought of doing the failed patch manually. But couldn't understand what
to do.
Please let me know what I am doing wrong and what I should be doing.
Thanks and Regards
Jayashankar

Try this patch:
http://git.postgresql.org/gitweb/?p=postgresql.git;a=commitdiff;h=068e08eebbb2204f525647daad3fe15063b77820
BTW, please don't cross-post to multiple PG mailing lists; there's very seldom
a good reason to do that.
