URGENT - startup process (PID 29541) was terminated by signal 6

Our Opteron DB server had a problem with its RAID controller requiring
an immediate shutdown of our Postgres server (8.1.3 on FreeBSD 6.0
release number 10). We used kill -QUIT on the postmaster PID.

After repairing and rebooting the server we tried to start Postgres and
get the following:

2006-10-06 12:32:40 CDT FATAL:  the database system is starting up
2006-10-06 12:32:40 CDT FATAL:  the database system is starting up
2006-10-06 12:32:40 CDT PANIC:  heap_clean_redo: no block
2006-10-06 12:32:40 CDT LOG:  startup process (PID 29541) was terminated
by signal 6
2006-10-06 12:32:40 CDT LOG:  aborting startup due to startup process
failure


At shutdown we had the following:

2006-10-06 12:08:48 CDT PANIC:  right sibling is not next child in
"winddir_idxu"
2006-10-06 12:08:48 CDT STATEMENT:  VACUUM ANALYZE VERBOSE
2006-10-06 12:08:49 CDT LOG:  server process (PID 91933) was terminated
by signal 6
2006-10-06 12:08:49 CDT LOG:  terminating any other active server processes

Anything I can do?

Um, were you running with full_page_writes off?  Bad idea in 8.1 :-( ...
especially on hardware that turns out to not be 100% reliable.

I think your only hope of restarting the database is to use
pg_resetxlog.  This is likely to leave you with some database
corruption, in the form of partially applied recent transactions.
I'd recommend a dump and reload, or at least REINDEXing all the
indexes, to forestall problems from that.  While you are at it,
update to 8.1.4.

            regards, tom lane

The manual [1] says that full_page_writes is ignored and always treated
as if it was set to on. Is it wrong?

Well, early versions of 8.1.X did honor full_page_writes, but 8.1.4
disabled it.
