Subject: [GENERAL] Postgresql segmentation fault at slot_deform_tuple

I'm running PostgreSQL 9.1.3 on x86_64-unknown-linux-gnu, compiled by gcc (GCC) 4.4.6 20110731 (Red Hat 4.4.6-3), 64-bit

on CentOS release 6.2 (Final)
Recently we encountered postmaster segfault, what the core dump gives me is:

Any help would be really appreciated.
