    postgresql plugin: Added support for protocol versions less than 3.
    
    Support for passing parameters to a query was added in protocol version 3
    which was introduced in version 7.4 of PostgreSQL (later version still support
    earlier protocol versions though). If that is not available, we now fall back
    to PQexec() if no parameters have been specified. Else, we skip the query and
    report an error.

    postgresql plugin: Fixed determination of 'max_params_num'.
    
    When adding the default queries to a database definition, 'max_params_num' has
    not been updated at all, resulting in a failed assertion during query
    execution. This is now fixed by splitting the common code for adding a query
    definition to a database definition into a new function and using that
    function where appropriate.

    postgresql plugin: Added "disk_usage" query.
    
    This is a new default query which collects the on-disk size of a database in
    bytes. A new type "pg_db_size" has been added to types.db for this purpose.
    
    The documentation in collectd.conf(5) and collection.cgi have been updated to
    reflect this change.

    postgresql_default.conf, postgresql plugin: Split default queries by category.
    
    The default queries have been split as follows:
    
     | old            | new                                |
     +----------------+------------------------------------+
     | database       | backends, transactions             |
     | user_tables    | queries, query_plans, table_states |
     | io_user_tables | disk_io                            |
    
    This allows for a more fine-grained control over which statistics are to be
    collected.
    
    The documentation and default queries definition have been updated to reflect
    this change.
