Re: Missing pg_clog files

No, the file needs to be nothing but hex value 55 throughout.  The
attachment I sent earlier is just that:

smarlowe@sawyer:~$ hexdump 55
0000000 5555 5555 5555 5555 5555 5555 5555 5555
*
0040000

i.e. all 55s, all the time, not the ascii numbers 5 and 5, but the hex
value.  The actual file is ascii the letter U over and over:

smarlowe@sawyer:~$ head -c 100 55
UUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU
UUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU

and so on.
