...G...PS. [DEV-558] Added support for bootstrapping a PostgreSQL database

Added a new defmacro for bootstrapping a new db in the local server. The macro
is influenced by the PSQLUSER and DBNAME properties that will be passed to the
ant command line by jenkins.
The DBNAME property is the same used for bootstrapping the mysql database, so
in this case the database names for both will be consistent.

With this commit also changed the mysql user property from DBUSER to MYSQLUSER.
