Hi Tom,
Sorry about the cross-post.
I am not aware of the procedures for patch etc.
Could you please tell me how to use the patch ?
I have already compiled and got the postgres server.
So please let me know the process of patching or kindly point me to a link which explain this.
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.
