database name to the OS user if not specified on the command line.
Also, pg_ctl will attempt to connect to the database on a start or
restart to confirm that it is running.
Once again: Thanks for the proposals.
I am not quite sure if files in /usr/local/etc/periodic/ are run, but I guess so. The command grep -ir sql . in this directory shows:
./daily/502.pgsql:# $FreeBSD: /tmp/pcvs/ports/databases/postgresql92-server/files/502.pgsql.in,v 1.4 2011-10-18 09:03:32 girgen Exp $

./daily/502.pgsql: su -l ${daily_pgsql_user} -c "vacuumdb ${daily_pgsql_vacuum_args}"
Seems pretty harmless to me. And in any case, it only runs once daily.
I am pretty sure I have to make a fresh install and import the important databases from dump files. At least, that would show if it is the database configuration or something outside the database server that creates the errors. I am not happy to do it, but I think I have to...
