Postgres_exporter does not support PostgreSQL 17

[sdayvz]

Hi,
I use Postgres_exporter 0.17.1 PostgreSQL 17, Grafana 12.0.1, Prometheus 3.4.0 on Rocky 8.

But some Grafana graphics are empty which are about checkpoint and bgwriter.

I check graphics' metrics and I see some old PostgreSQL statistic tables' columns in queries.

For example:

Checkpoint stats graphic's query:
rate(pg_stat_bgwriter_checkpoint_write_time{instance="$instance"}[$interval]) or
irate(pg_stat_bgwriter_checkpoint_write_time{instance="$instance"}[5m])

Buffers (bgwriter) query:
rate(pg_stat_bgwriter_buffers_alloc{instance="$instance"}[$interval]) or
irate(pg_stat_bgwriter_buffers_alloc{instance="$instance"}[5m])

But there is not buffers_alloc column on pg_stat_bgwriter table in PostgreSQL 17.

Is it a bug?
Thanks.
