Hi all,
My wonderful colleagues in charge of our production database have screwed up royally. They managed to corrupt the production database by having two instances of postgresql talking
to the same database/same filesystem/same time. Now, they'd like me to fix it. Sigh...
BTW, this is a V9.2.2 system, and the database will still start, but the logs are full of reports pf invalid page header errors. One thing I'm looking at is doing a "ps -ef | grep
postmaster", I see "service postgresql-9.2 start" uses:
postmaster -D /opt/datacenter -i -N 384 -p 5431
Now, I know what the -D and -p are doing, but I'm not sure what -i and -N are for, and my internet search hasn't turned up much. Anybody know?

PS. Any suggestions beyond setting zero_damaged_pages=true and then running a vacuum would also be appreciated.
