Postgres: pick the database by URL, copy-db, tests on both

Browse Source 
- IPX_DATABASE_URL (postgres://...) picks the database; unset, it is the SQLite
  file as before. Passwords are taken out of anything logged.
- `ipx copy-db <state.db>` copies every table into the empty database the URL
  names, in one transaction, and moves the id counters past the copied ids. A
  copy of production went across in 14s with every count and column
  fingerprint identical.
- With IPX_TEST_DATABASE_URL set, each test gets a Postgres schema of its own;
  all 79 pass on both databases. Fixtures write booleans as true/false.
- Sorts say where an item with no value goes (NULLS FIRST going up, LAST going
  down): SQLite counts NULL as smallest, Postgres as largest, so "largest first"
  on Postgres led with every item that has no file. Tested on both.
