Yes, and how exactly you do not include them?
For example - this is my backup script that is executed nightly:
-------------------------------------------------------------------
PSQL=/usr/local/pgsql/bin/psql
PG_DUMP=/usr/local/pgsql/bin/pg_dump
PG_DUMPALL=/usr/local/pgsql/bin/pg_dumpall
$PG_DUMPALL -U postgres --globals-only > $BACKUPDIR/pg_globals.sql
for db in `$PSQL -U postgres -d template1 -t -c "SELECT datname FROM
pg_catalog.pg_database WHERE datname "\!"~ 'template(0|1)';"`
do
echo -n -e "Dumping database $db...\t\t"
$PG_DUMP -U postgres --format=c $db > $BACKUPDIR/$db.dump
echo "done."
done
-------------------------------------------------------------------
Guess what? There was a special command-line parameter for including
large objects in the custom/tar dump until version 8.1
(http://www.postgresql.org/docs/8.0/static/app-pgdump.html, look for
"--blobs"). Now they are included by default AND could not be excluded,
at least I could not find a way to do that
(http://www.postgresql.org/docs/8.1/static/app-pgdump.html).
So what are you suggesting?
