Postgresql 9.0.13 core dump

Hello all,

I am having core dump on Postgres 9.0.13 with the message "...was
terminated by signal 10: Bus error...".

So, I set a PID on the log file to capture specific PID that causing this
crash. After, several crashes, I finally got the PID that causing this
crash. But I am still not convinced that this process that causing this
crash. That is the reason why I sent out this email, hoping anybody can
help me or have had this experience before.

Based on the PID on the log file, the crash happened while the application
was trying to update a table's field with binary (PDF) content. The
datatype of this field is TEXT.

I am using FreeBSD 9.1 host that has 3 database jails. One of them is this
database that causing core dump. Other databases are working fine.

Below is the information about the core dump.

Any help is appreciated.

Thanks!
-Laurent
