DEV: Set synchronous_commit to off in start_test_db ()
Why this change?

In https://www.postgresql.org/docs/current/non-durability.html, it is
recommended to turn off `synchronous_commit` in environments where
durability is not important. The `start_test_db.rb` script is mainly
used in the CI environment where durability is not important at all.
