node tests/load/run.js --postgres puts the scratch daemon in IPX_TEST_DATABASE_URL, the database
the Rust tests already use on Postgres, ipodderx_test on the databases project's server, in a
schema of its own, ipx_load, dropped and made again each run as /tmp/ipx-load is wiped. The URL
is in /src/.envrc, taken from ipx.env. It is production's server and role, so the harness refuses
a database whose name does not end in _test, and hands psql the password in its environment,
where no other process on Tower can read it. psql comes from /src/install.sh.
After seeding it runs ANALYZE: a schema filled seconds before has no planner statistics until
autovacuum gets there, which it did partway through a test, and the search's p95 swung between
40ms and 166ms from run to run. Analyzed first, three runs gave 37-38ms.
Each budget now has a value for each database, about twice what it measures on Tower: Postgres
answers the feed list at p95 54ms to SQLite's 242, having no one connection to queue for (#136).
Running it found #140.
