v0.4.6

* Fix issue #173 - 32 and 64mb unit sizes were not supported in pg_settings.

v0.4.5

* Add commandline flag to disable default metrics (thanks @hsun-cnnxty)

v0.4.4

* Bugfix for 0.4.3 which broke pg_up (it would always be 0).
* pg_up is now refreshed based on database Ping() every scrape.
* Re-release of 0.4.4 to fix version numbering.

v0.4.2

* Adds the following environment variables for overriding defaults:
    * `PG_EXPORTER_WEB_LISTEN_ADDRESS`
    * `PG_EXPORTER_WEB_TELEMETRY_PATH`
    * `PG_EXPORTER_EXTEND_QUERY_PATH`

* Add Content-Type to HTTP landing page.
* Fix Makefile to produce .exe binaries for Windows.

v0.4.1

* No code changes to v0.4.0 for the exporter.
* First release switching to tar-file based distribution.
* First release with Windows and Darwin cross-builds.\\

v0.4.0

* Fix panic due to inconsistent label cardinality when using queries.yaml with
  queries which return extra columns.
* Add metric for whether the user queries YAML file parsed correctly. This also
  includes the filename and SHA256 sum allowing tracking of updates.
* Add pg_up metric to indicate whether the exporter was able to connect and
  Ping() the PG instance before a scrape.
* Fix broken link in landing page for `/metrics`

v0.3.0

* Add support for PostgreSQL 10.

v0.2.3

* Add support for the 16kB unit when decoding pg_settings. (#101)

v0.2.2

* Fix DSN logging. The exporter previously never actually logged the DSN when
  database connections failed. This was also masking a logic error which could
  potentially lead to a crash when DSN was unparseable, though no actual
  crash could be produced in testing.

v0.2.1

* Ignore functions that cannot be executed during replication recovery (#52)
* Add a `-version` flag finally.
* Add confirmed_flush_lsn to pg_stat_replication.
