+On UNIX, you might want to select a UNIX socket for the transport,
+either the default socket as defined by the PGHOST environment variable:
+{{{
+postgres://user:password@/database
+}}}
+or a specific one:
+{{{
+postgres://user:password@/database?host=/path/to/socket/dir
+}}}
+
 Note that with PostgreSQL you will have to create the database before running
 `trac-admin initenv`.

-And didn't work uppercase trac-user-name
+See the [http://www.postgresql.org/docs/ PostgreSQL documentation] for detailed instructions on how to administer [http://postgresql.org PostgreSQL].
+Generally, the following is sufficient to create a database user named `tracuser`, and a database named `trac`.
 {{{
-sudo su - postgres -c createdb trac
-sudo su - postgres -c psql trac
-CREATE USER trac-user-name WITH PASSWORD 'trac-pass-name';
+createuser -U postgres -E -P tracuser
+createdb -U postgres -O tracuser -E UTF8 trac
+}}}
+When running `createuser` you will be prompted for the password for the user 'tracuser'. This new user will not be a superuser, will not be allowed to create other databases and will not be allowed to create other roles. These privileges are not needed to run a trac instance. If no password is desired for the user, simply remove the `-P` and `-E` options from the `createuser` command.  Also note that the database should be created as UTF8. LATIN1 encoding causes errors trac's use of unicode in trac.  SQL_ASCII also seems to work.
+
+Under some default configurations (debian) one will have run the `createuser` and `createdb` scripts as the `postgres` user.  For example:
+{{{
+sudo su - postgres -c 'createuser -U postgres -S -D -R -E -P tracuser'
+sudo su - postgres -c 'createdb -U postgres -O tracuser -E UTF8 trac'
 }}}
 
-(Just to remind you, if you don't have a sudo/su setup, you just need to do the createdb and psql statements. That threw me the first couple of times I read this.)
+Trac uses the `public` schema by default but you can specify a different schema in the connection string:
+{{{
+postgres://user:pass@server/database?schema=yourschemaname
+}}}
+
+=== MySQL Connection String ===
+
+If you want to use MySQL instead, you'll have to use a
+different connection string. For example, to connect to a MySQL
+database on the same machine called `trac`, that allows access to the
+user `johndoe` with the password `letmein`, the mysql connection string is:
+{{{
+mysql://johndoe:letmein@localhost:3306/trac
+}}}
