Backing up the entire database using `pg_dump`, with parallelism 1 (use more on
larger machine with fast disks; try 4 or 8?), assuming the database name is
'fatcat', and the current user has access:
pg_dump -j1 -Fd -f test-dump fatcat

+
+The `extras/quick_dump.sql` script will dump abstracts and identifiers as TSV
+files to `/tmp/`. Pretty quick; takes about 15 GB of disk space (uncompressed).
