| Failover | :white_check_mark: | Replicas are tested with a health check. If a health check fails, remaining replicas are attempted; see below for algorithm description and examples. |
| Statistics | :white_check_mark: | Statistics available in the admin database (`pgcat` and `pgbouncer`) with `SHOW STATS`, `SHOW POOLS` and others. |
| Live configuration reloading | :white_check_mark: | Reload supported settings with a `SIGHUP` to the process, e.g. `kill -s SIGHUP $(pgrep pgcat)` or `RELOAD` query issued to the admin database. |
| Client authentication | :x: :wrench: | On the roadmap; currently all clients are allowed to connect and one user is used to connect to Postgres. |
| Client authentication | :white_check_mark: :wrench: | MD5 password authentication is supported, SCRAM is on the roadmap; one user is used to connect to Postgres with both SCRAM and MD5 supported. |
| Admin database | :white_check_mark: | The admin database, similar to PgBouncer's, allows to query for statistics and reload the configuration. |
