Is it acceptable to attach text files to email in this mailing list?  I know 
some don't like it.
I've found the script file (/usr/share/postgresql/postgresql-script) and that 
message is in there but the coding in it is beyond my expertise as i can only 
do basic stuff.
Here is a cut and paste of part of it.

----- /usr/share/postgresql/postgresql-script ----

PG_SYSCONFIG=/etc/sysconfig/postgresql
test -f $PG_SYSCONFIG && . $PG_SYSCONFIG

eval DATADIR=${POSTGRES_DATADIR:-~postgres/data}
OPTIONS=${POSTGRES_OPTIONS}
INITDB_OPTS=${POSTGRES_INITDB_OPTS}
PIDFILE=$DATADIR/postmaster.pid

# 
if test -r $DATADIR/PG_VERSION ; then
    DATA_VERSION=$(cat $DATADIR/PG_VERSION)
    POSTGRES=/usr/lib/postgresql$(echo -n $DATA_VERSION | tr -d .)/bin/
postgres
fi
if test -x /usr/bin/postgres; then
    ACTIVE=$(readlink -q -f /usr/bin/postgres)
    test -z "$POSTGRES" && POSTGRES="$ACTIVE"
fi
if test -n "$DATA_VERSION"; then
    if test -z "$ACTIVE" -o "$ACTIVE" != "$POSTGRES"; then
    echo " Your database files were created by PostgreSQL version 
$DATA_VERSION."
    if test -x "$POSTGRES"; then
        echo " Using the executables in $(dirname $POSTGRES)."
    else
        echo " Could not find executables for this version."
        echo " Please install the PostgreSQL server package for version 
$DATA_VERSION."
    fi
    fi
elif test -z "$ACTIVE"; then
    echo " Cannot find an active PostgreSQL server binary. Please install one 
of the PostgreSQL"
    echo " server packages or activate an already installed version using 
update-alternatives."
fi
if test ! -x "$POSTGRES"; then
    exit 1
fi
