I just tried several times to make sure I didn't do anything wrong. I use pg_dump -U postgres -E UTF8 -F c -b -v -a dbcontent -f data.backup then pg_restore -a -d dbcontent data.backup to restore a db, and the data dir's size on the source machine is 56GB, after I restored data on the target machine, it 130GB, I did vacuum full but nothing changed. is there anything wrong with the db? -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
