Step 1: redesign your DB to *NOT* use large objects. It's an old, slow and
unmaintained data type. The data type is what you should use.
Step 2: show us the "before" df output, the whole pg_dump command, and the
"after" df output when it fails. "du -c --max-depth=0 $PGDATA/base" also
very useful.
And tell us what version you're using.
