This will be populated with default values which can then be customised for the
particular use case.
Additionally the create command can be used to initialize (and update) a
Postgres database which can be used by the ``postgres`` output processor.
The most of database connection parameters have a default value however they can
be overridden via command line arguments. When initializing the database WA will
also save the supplied parameters into the default user config file so that they
do not need to be specified time the output processor is used.
As an example if we had a database server running on at 10.0.0.2 using the
standard port we could use the following command to initialize a database for
use with WA::
wa create database -a 10.0.0.2 -u my_username -p Pa55w0rd
This will log into the database server with the supplied credentials and create
a database (defaulting to 'wa') and will save the configuration to the
``~/.workload_automation/config.yaml`` file.
With updates to WA there may be changes to the database schema used. In this
case the create command can also be used with the ``-U`` flag to update the
database to use the new schema as follows::
wa create database -a 10.0.0.2 -u my_username -p Pa55w0rd -U
This will upgrade the database sequentially until the database schema is using
the latest version.
