Re: Incomplete Startup Packet on startup and when pg_maintenance --analyze runs in cron

["Jennifer Redman" <jenred@xxxxxxxxx>]

It looks like this is a problem with the Ubuntu package postgresql-common.  I opened a bug there:

https://bugs.launchpad.net/ubuntu/+source/postgresql-8.3/+bug/309496

And for those of you who may have the same issue:

Running
# /etc/init.d/postgresql-8.3 autovac-restart
 * Restarting PostgreSQL 8.3 autovacuum daemon

Results in:
 * Error: PostgreSQL 8.1 and above has an integrated autovacuum daemon which cannot be controlled by this program.

Looks like /etc/cron.d/postgresql-common

# Run VACUUM ANALYSE on all databases every 5 hours if pg_autovacuum is not
# running
2 0,5,10,15,20 * * 1-6 root if [ -x /usr/sbin/pg_maintenance ]; then /usr/sbin/pg_maintenance --analyze >/dev/null; fi

Is deprecated for postgresql versions 8.1 and higher and needs to be commented out by default in those packages.

The same error message appears on start-up
( incomplete startup packet)

but I could not figure out where in /usr/share/postgresql-common/init.d-functions the pg_maintenance script was being called.

Additionally,

Running:

#/sbin/pg_maintenance --analyze

results in:
Skipping cluster 8.3/main since autovacuuming is enabled for it

and the subsequent:

2008-12-18 15:21:18 PST LOCATION: ProcessStartupPacket, postmaster.c:1396

in /postgresql-8.3-main.log

I'm get the following error in the logs at startup and at the exact interval that -x /usr/sbin/pg_maintenance ]; then /usr/sbin/pg_maintenance --analyze appears to run in cron:

This seems like a missed configuration option -- but I'm not sure where.  Any ideas?
