* [BUGFIX] Make collectors not fail on null values #823

Signed-off-by: SuperQ <superq@gmail.com>

BREAKING CHANGES:

Please note, the following features are deprecated and may be removed in a future release:
- `auto-discover-databases`
- `extend.query-path`
- `constantLabels`
- `exclude-databases`
- `include-databases`

This exporter is meant to monitor PostgresSQL servers, not the user data/databases. If
you need a generic SQL report exporter https://github.com/burningalchemist/sql_exporter


is recommended.

* [CHANGE] Adjust log level for collector startup #784
* [CHANGE] Move queries from queries.yaml to collectors #801
* [CHANGE] Deprecate extend queries feature #811
* [CHANGE] Deprecate additional database features #815
* [CHANGE] Convert pg_stat_database to new collector #685
* [ENHANCEMENT] Supports alternate postgres:// prefix in URLs #787
* [BUGFIX] Fix pg_setting different help values #771

BREAKING CHANGES:

This release changes support for multiple postgres servers to use the
multi-target exporter pattern. This makes it much easier to monitor multiple
PostgreSQL servers from a single exporter by passing the target via URL
params. See the Multi-Target Support section of the README.

* [BUGFIX] Add dsn type for handling datasources #678

* [BUGFIX] Avoid parsing error from bogus Azure Flexible Server custom GUC #587

This moves the metrics that are queried from pg_stat_bgwriter into a dedicated collector instead of dynamically generating queries and metrics from a map. It renames some metrics including adding the `_total` suffix on all of the counters to match prometheus standards. This implementation uses QueryRowContext to allow for later addition of context for cancellation. From the Postgres documentation, it states that there is one line per WAL sender process, but it is unclear how to differentiate between them in any meaningful way. When querying the table, there is no column to identify the row, only metrics about bgwriter.

Converts the pg_database metrics from queries.yaml to a built in collector. This is enabled by default because it is not likely to be a performance problem and likely very useful data.
