Description: Corrupted Table
Details:

Today a table corrupted and I started getting:

"invalid page header in block 900 of relation pg_tblspc/32041/138911/187737"

on all selects on a given table.

RhodiumToad & StuckMojo (and a few others) helped me track it down. The
page in question looked like this:

http://pgsql.privatepaste.com/83JfmQGtS5

RhodiumToad gave me this command to repair the table:

printf '\x00\x01\x40\x03\x00\x20' | dd of=pg_tblspc/32041/138911/187737 bs=1
conv=notrunc seek=7372812 count=6

The reason they asked me to report this is that it appears this occured when
a disk filled up while pg_dump was running.

On this system df -h shows:

/dev/sda1 65G 23G 39G 38% /
varrun 4.0G 48K 4.0G 1% /var/run
varlock 4.0G 0 4.0G 0% /var/lock
udev 4.0G 40K 4.0G 1% /dev
devshm 4.0G 0 4.0G 0% /dev/shm
/dev/sdb1 136G 23G 107G 18% /data

/dev/sda1 is where the pgdata directory is.
/dev/sbd1 is where the tablespace is.

/sda1 is the drive that filled up while running a pg_dump.

If there is any additional info I can provide please let me know.
