postgresql 9.2.1 dumps core on SmartOS(solaris) when the OS is rebooted - Mailing list pgsql-bugs

I've got postgres 9.2.1 32bit running in production on SmartOS(solaris) =
with synchronous remote-write replication enabled. At some point, both =
of the boxes were rebooted. Upon reboot, one of the postgres instances =
dumps core with the following stack trace:
