* Added missing table that should store a planet's resources data
(income and upkeep for each type of resource).
* Modified resource definition functions and universe generator to
initialise planet resource records as well
* Heavy clean-up in resource definition function unit tests
* Changed the way mining settings work: use a priority value (between 0
and 4) as the weight. Leaving them as they were before would have caused
numerous problems (and a lot of unnecessary code to work around them)
* Empire mining settings will be created along with the empire's own
record. By default all natural resources will have weight = 2.
* Added a set of four stored procedures which can be used to update an
empire's mining settings, including planet-specific settings. The
emp.mset_update_start() function can be used to start an update (on an
empire's settings if there is only one parameter, or on a planet's
settings if there are two parameters); the emp.mset_update_set() and
emp.mset_update_apply() functions are then used to modify the settings
and apply the changes, respectively.
* Added user mapping on the "remote" logging database for the
administrative user. This allows calls to sys.write_sql_log() to succeed
when they are executed by code with administrative privileges.
* Added test suites for both the link to the database and the function
itself.
* Replaced RAISE NOTICE with actual logging in the universe generator
* The main loader script has been updated to generate the list of files
it needs to load automatically. As a consequence, files that contained
manually-maintained lists of scripts have been removed, and definition
directories have been renamed accordingly.
* PostgreSQL extension loading and configuration has been moved to a
separate script to be loaded automatically in the main transaction.
* Data and function definition scripts that had the -data or -functions
suffix have been renamed (the suffix is unnecessary).
* Unit tests have been reorganised to follow the definition's structure.
* Documentation has been improved
* The universe generator has been modified to generate resource
providers. The code attempts to keep the universe balanced according to
the natural resources definitions.
* Fixed privileges on both variants of defs.uoc_natural_resource()
* Added user unit tests which check execution privileges on all (new)
stored procedures and INSERT/UPDATE/SELECT/DELETE privileges on all
(new) tables
* Added in-base logging through a foreign data wrapper, which is only
possible using PostgreSQL 9.1
* Renamed database-related configuration files to indicate that they are
samples, and added the "real" names to the Git ignore list. Server
distribution modified accordingly.
* Removed PL/PgSQL registration (it was only necessary on 8.4)
* Added pgTAP SQL definitions and a script which will (hopefully) be
executed by the build system after the main Java build in order to
execute database unit tests. The script supports both admin- and user-
level testing. I also added a few tests to make sure the testing framework
actually runs them.
* Added documentation about the database definitions structure
