> 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....

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

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
