Bug reference: 7969
Logged by: Yunong Xiao
Email address: yjxiao(at)gmail(dot)com
PostgreSQL version: 9.2.2
Operating system: SmartOS (Solaris)
Description:
I have an instance of postgresql 9.2.2 running on Solaris. At some point the
zone the postgresql was running on was restarted (effectively a power cycle)
and postgresql consistently crashes on recovery with the following log
snippet: (full log and postgresql.conf attached at the end of this email)

2013-03-15 22:00:49.515 UTCFATAL: incorrect local pin count: 2
I am running postgres on ZFS with fsync=on, which as far as I can tell,
guarantees that there can be no data corruption. I have included the
postgres data directory as a tarball here:
https://download.joyent.com/pub/postgresql/corrupted-pg.tar and this problem
can be reproduced by untarring the data directory and running as the
postgres user `postgres -D <path_to_data_dir>`
Full postgresql logs:

corrupted and you will have to use the last backup for recovery.
