Hmm, that sounds like the issue discussed here: 
http://www.postgresql.org/message-id/50C7612E.5060008@vmware.com, and 
fixed by this commit:

http://git.postgresql.org/gitweb/?p=postgresql.git;a=commit;h=fb565f8c9616ec8ab1b5176d16f310725e581e6e

Can you check if you still see that behavior with REL9_2_STABLE?
