Thread: indices are crashed after installation of rpm

hello all,
we are running PostgreSQL 7.0.2 on Solaris 2.6,/x86 compiled by gcc 2.8.1.
For installation Postgres on 70 Solaris-2.6 server we built packages
(SVR4-style).

The first time we installed Postgres everything was ok. But after a new
installation of the package ( - same Postgres version! - just the starting
script changed) all indices where damaged (this is reproducible).

In the installation script the postmaster is stopped and started. Is it
possible the stopping and starting is crashing the indices,
because sometimes just stopping and starting the postmaster ist crashing the
indices (not reproducible)?

Has someone any idea what's wrong, do you need more informations?
greetings,
Peter


this ist the starting/stopping script S99postgres:

#!/bin/sh

umask 077

killdaemon()
{
        PIDs=`ps -u postgres | sed '/PID/d;s/ \{1,\}/ /g' | cut -d" " -f2 |
sort -rn`
        [ -n "$PIDs" ] && kill $PIDs
        [ -f /tmp/.s.PGSQL.5432 ] && rm -f /tmp/.s.PGSQL.5432
        echo "postmaster stopped"
}

startdaemon()
{
        su postgres -c /export/home/postgres/start_postgres
        echo "postmaster started"

        su postgres -c /export/home/postgres/chk_user \
        && su postgres -c /export/home/postgres/create_user
}

case "$1" in
        'start')
                startdaemon
                ;;
        'stop')
                killdaemon
                ;;
        'restart')
                killdaemon
                startdaemon
                ;;
        *)
                echo "Usage: $0 { start | stop | restart }"
                ;;
esac

exit 0

LD_LIBRARY_PATH=/usr/openwin/lib:/usr/dt/lib:/opt/local/DWH/lib
export PATH LD_LIBRARY_PATH

PGLIB=/DWH/lib
PGDATA=$HOME/data
export PGLIB PGDATA

postmaster -i -D /export/home/postgres/data >> /tmp/postgres.log

Do you build with --enable-locale?  If so, check to see if the
postmaster is being restarted with a different locale setting
(different LANG or LC_xxx environment variables).  Any change
in the effective sort order defined by the locale setting will
leave text indices corrupted.  Unfortunately, system boot scripts
very often run with different environment than user shells do...

7.1 has some defenses against this: the locale prevailing at initdb
time is saved, and adopted by every subsequent postmaster start.
But in older releases you just have to be careful.

There are at least two components in this you might consider upgrading:
- PostgreSQL itself (to 7.0.3 or, even better, 7.1)
- gcc. Gcc 2.8.1 was a bit of a dead end in gcc development; by the time
  it was released, the EGCS development effort was quite a bit more
  advanced. The EGCS work has been incorporated into gcc 2.95(.x), and
  personally I trust gcc 2.95.3 a lot more than I'd trust 2.8.1.

HTH,
Ray
