Improve pg dump&restore

time pg_dump -j 8 -Fd -f /tmp/newout.dir fsdcm_external

PG_RESTORE | always use tuning for postgres.conf and format-directory and -j options

work_mem = 32MB
shared_buffers = 4GB
maintenance_work_mem = 2GB
full_page_writes = off
autovacuum = off
wal_buffers = -1

time pg_restore -j 8 --format=d -C -d postgres /tmp/newout.dir/
