I saw the above 2 types of errors (transaction status, segv) yesterday on
a box that turned out to have issues writing files correctly to disk. I
wrote a tool to write a large file to disk and then reopened the file
to read/verify the contents and it would fail every so often (like 1-5% of
the time.) What puzzles me is that the machine would work at all with an
issue like that. Turning on/off the battery backed cache had no effect.
The machine has ECC memory, but I tested that as well but it turned up
nothing. I am using PostgreSQL 7.4.1.
