After a successful same-server test of the postgres on-line backup
process, I tried a test from a remote server to simulate a process
I'll need to do in a production environment soon.

After a step-by-step on-line backup, I saw the following in my logs:

2006-03-21 10:38:53 CST 1412 :LOG:  archive recovery complete
2006-03-21 10:38:53 CST 1412 :LOG:  could not truncate directory
"pg_multixact/offsets": apparent wraparound
2006-03-21 10:38:53 CST 1412 :LOG:  could not truncate directory
"pg_multixact/members": apparent wraparound
2006-03-21 10:39:22 CST 1412 :LOG:  database system is
ready2006-03-21 10:39:22 CST 1412 :LOG:  transaction ID wrap limit is
2147484146, limited by database "postgres"

followed by dozens of these:

2006-03-21 10:39:22 CST 2499 :LOG:  invalid server process ID -1

None of these are errors, but they don't seem like healthy messages
nonetheless. I don't see much discussion of them in the archives. Are
they cause for concern?
