pg dump -h localhost -p 5432 -U postgres -d mydb -t my table     backup sql   You can take the backup of a single table but I would suggest to take the backup of whole database and then restore whichever table you need  It is always good to have backup of whole database   9 ways to use pg dump

As an addition to Frank Heiken s answer  if you wish to use INSERT statements instead of copy from stdin  then you should specify the --inserts flag  pg dump --host localhost --port 5432 --username postgres --format plain --verbose --file   lt abstract file path gt   --table public tablename --inserts dbname  Notice that I left out the --ignore-version flag  because it is deprecated
