Re: pg_restore test procedures (a bit OT) - Mailing list pgsql-admin

> I was just wondering if anyone has any clever way of testing their backups
taken with pg_dump on a daily basis?
I have a daily bash script to backup of one of my databases to file, then
file to tape, which I test restore once per week. I've changed some of my
variables to hard-coded strings to make it shorter and easier to understand
at a quick read. Yes I know it's kinda fschked but it's working atm. I'll
tidy it up eventually....

<snip>
if [ "$DAY" = "Mon" ] ; then
    echo "Test restoring database..." >> $LOG_FILE

    if [ 1 -eq 1 ] ; then
        # Debugging
        $ECHO "Restoring from:           ${BACKUP_PATH}"
        $ECHO "Restoring to Directory:   ${TMPDNAME}"
        $ECHO "Restore Database:         ${DBNAME}${DATESTRING}"
        $ECHO "Restore Source File:      ${TMPFILE}"
    fi

    echo -n "Extracting database dump from tape... "
    tar xf /dev/st0 --directory /tmp
    if [ $? -ne 0 ] ; then
        echo "FAIL"
        echo "   Failed to Restore from /dev/st0 to /tmp/" >>
$LOG_FILE
        SHOW_ERR=true
    fi

    if [ ${SHOW_ERR} != true ] ; then
        ### Note: $DATESTRING = yymmdd (eg. 080519)
        echo "Creating new database ${DBNAME}${DATESTRING}" >>
$LOG_FILE
        /usr/local/bin/psql --command "CREATE DATABASE
${DBNAME}${DATESTRING} ENCODING = 'SQL_ASCII';" > /dev/null
        if [ $? -eq 0 ] ; then
            echo "Restoring /tmp/psqldump.sql.502 to
${DBNAME}${DATESTRING}" >> $LOG_FILE
            /usr/local/bin/psql ${DBNAME}${DATESTRING} <
/tmp/psqldump.sql.502
        else
            echo "Failed to Create Database!" >> $LOG_FILE
            SHOW_ERR=true
        fi
    fi

Perhaps something like this: (it's Monday morning, so I might be suggesting
something stupid)
LOG=`su - $PGUSER -c "pg_restore -h localhost -U postgres --disable-triggers
-c -d $database $backup_dir/$server-$database-data.gz"`
echo $LOG >> $logfile
