postgresql plugin: Simplified transaction handling a bit.
Don't set any next commit time after committing a transaction but only when
starting a new transaction. This way, db->next_commit == 0 always means that
we're outside of a transaction. Also, this removes the need to restart a
transaction right away. Rather, the write callback will take care of that the
next time it gets any data.

collectd.conf(5): Documented the postgresql FLUSH support.
postgresql plugin: Added support for "flushing" data.
This may be used to commit a PostgreSQL writer's transaction. Two different
types of flush callbacks are registered:
- postgresql: Flush *all* databases.
- postgresql-<database>: Flush the database named '<database>' only.
This may be used to commit a PostgreSQL writer's transaction. Two different
types of flush callbacks are registered:

postgresql plugin: Fixed unregistering of write callbacks.
Rather than unregistering some callback for each writer for each database,
unregister the single callback for each database only.
Rather than unregistering some callback for each writer for each database,

postgresql plugin: Unregister all writers on shutdown.
This will make sure that all pending transactions will be committed. Else, the
open transactions would be rolled back by the PostgreSQL backend when closing
the connection.
In order to do so, all database connections are now stored in a plugin-global
array (this will also make further changes possible). Also, a ref-count has
been added to the database object in order to support "deleting" an object
twice when having it in use by a connection doing queries and writes.

Also, make sure to acquire the database lock before that in order to wait for,
for example, outstanding writers.

The failed query inside the transaction causes the transaction to be aborted
and all subsequent queries to fail as well.

If specified, this option causes a writer to put several updates into a single
transaction. This transaction will last for the specified amount of time (in
seconds). By default, each update would be executed in a separate transaction
causing quite some overhead.

The array includes the stringified version of the data-source type, i.e.,
'gauge', 'counter', etc. This will enable the writer to treat different types
differently. However, when having 'StoreRates' enabled (the default) all types
will be 'gauge'. So, in most cases, this won't be used but it has been added
for completeness and to be safe for the future.

This function formats a cdtime_t value in ISO 8601 format (and ensures that
the string is null terminated).
postgresql plugin: Added generic support for writing values to a database.
This has been implemented by requiring the user to specify an SQL statement to
be used for storing a value-list in PostgreSQL. Usually, this should be done
by creating custom functions to take care of that.
The user specified statement will then be called by collectd with eight
arguments: time, host, plugin, plugin instance (or NULL), type, type instance
(or NULL), array of value names (data source names) and an array of the
values.
Two elements have been added to the config parser: A <Writer> block may be
used to name an SQL statement (specified using the 'Statement' option) to be
used for writing data. In a <Database> block, the new option 'Writer' may be
used to apply a writer to a database connection.
The current approach has two benefits: for one, a user may chose whatever
database layout best suits her needs. Also, it is very easy to experiment with
different approaches on how to structure the data in a database without the
need to modify the plugin. This can be done in SQL, which (hopefully) is the
language that people working with PostgreSQL databases like most ;-)
If it happens to turn out that some approach is rather superior, it may still
be re-implemented in a specific plugin in later versions.

network plugin: Do not forward received notifications.
The network plugin would send out all notifications it got through its
callback, even the ones it received itself and even when forwarding was
disabled.
With this patch the network plugin will only transmit notifications created
locally -- forwarding of notifications is not implemented due to missing
loop-detection. For loop-detection we would have to keep track of the last
timestamp of each notifications, and since each host/plugin/type/-instance
field may be empty, this is not as straight forward as with value lists. If
someone needs this, they will need to invest some work I'm afraid.

programm. KERN_PROC_ALL attribute keep for future purposes.
- Gets command argument failed for some processes as system and some
other. It led to error messages to console. Fix based on codebase of

- System and user CPU times turned out from the sum of miliseconds
