BREAKING CHANGES:
The logging system has been replaced with log/slog from the stdlib. This change is being made across the prometheus ecosystem. The logging output has changed, but the messages and levels remain the same. The `ts` label for the timestamp has bewen replaced with `time` , the accuracy is less, and the timezone is not forced to UTC. The `caller` field has been replaced by the `source` field, which now includes the full path to the source file. The `level` field now exposes the log level in capital letters.

Please note, the following features are deprecated and may be removed in a future release:
- `auto-discover-databases`

2021-03-01 12:48:14 +00:00

queries which return extra columns.

2021-03-01 12:48:14 +00:00
## 0.3.0 / 2017-10-23

* Add support for PostgreSQL 10.
2021-03-01 12:48:14 +00:00
## 0.2.3 / 2017-09-07
2021-02-26 14:17:36 +00:00

2021-02-26 14:17:36 +00:00
* 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.
2021-03-01 12:48:14 +00:00
## 0.2.1 / 2017-06-07

## 0.2.0 / 2017-04-18
2021-02-26 14:17:36 +00:00
* Major change - use pg_settings to retrieve runtime variables. Adds >180
new metrics and descriptions (big thanks to Matt Bostock for this work).
Removes the following metrics:
```
pg_runtime_variable_max_connections
pg_runtime_variable_max_files_per_process
pg_runtime_variable_max_function_args
pg_runtime_variable_max_identifier_length
pg_runtime_variable_max_index_keys
pg_runtime_variable_max_locks_per_transaction
pg_runtime_variable_max_pred_locks_per_transaction

pg_runtime_variable_max_standby_archive_delay_milliseconds
pg_runtime_variable_max_standby_streaming_delay_milliseconds
pg_runtime_variable_max_wal_senders
```
They are replaced by equivalent names under `pg_settings` with the exception of
```
pg_runtime_variable_max_standby_archive_delay_milliseconds
pg_runtime_variable_max_standby_streaming_delay_milliseconds
```
which are replaced with
```
pg_settings_max_standby_archive_delay_seconds
pg_settings_max_standby_streaming_delay_seconds
```
