Web Dev w/Clj 3e (vB17.0): Unknown dbtype - conman 0.8.4 broken. Fix: upgrade to 0.9.1

Title: Web Development with Clojure 3e (vB17.0): Unknown dbtype (ch1 tests) p 15

Using conman version 0.8.4 brings the following error:

ERROR in (test-messages) (connection.clj:199)
Uncaught exception, not in assertion.
expected: nil
  actual: clojure.lang.ExceptionInfo: Unknown dbtype: 
{:datasource #object[com.zaxxer.hikari.HikariDataSource 0x4953c5f8 "HikariDataSource (HikariPool-1)"]}

Upgrading conman to “0.9.1” is an easy solution.

For whoever in the future might look for this:

This is a typo-like mistake made by the author I believe. The example code was written with legacy subprotocol and subname while the author’s true intention is to use the preferred dbtype and dbname.

The paragraph right below the example code says:

In the preceding example, we’ve defined a connection for an instance of the PostgreSQL database by specifying the database type suing :dbtype key and a name using the :dbname key.

So we should really use these two instead.
