Subject: [PATCH 03/17] sql-exporter: Add additional settings.

This adds some memory-based settings (shared_buffers, work_mem,
maintenance_work_mem, effective_cache_size and max_wal_size), as well as some
notable settings one might want to expose e.g. in Grafana dashboards like
data_checksums, jit (v11+), max_worker_processes, random_page_cost,
seq_page_cost and checkpoint_timeout).

Subject: [PATCH 04/17] Dashboard: Add settings panels at the top.

This adds two rows of stat panels at the top that show key settings and values
of the instance:

 * server version, instance uptime, bnumber of cores, total memory
 * max connections
 * memory/wal related settings
 * data checksums/jit settings
 * number of checksum failures and oom kills

Subject: [PATCH 05/17] Dashboard: Update Checkpoints per Minute panel.

 * make (regular) timed checkpoints green and requested ones yellow
 * mention that requested checkpoints can also be wal- or backup-based
 * hardcode rate interval to 90s which seems to display well for most common
   checkpoint_timeout values
 * change y axis intervals to integers

Subject: [PATCH 10/17] Dashboard: Update Table Scans panels.

This changes the Sequential/Index Scans panels (that reported the total number
of seq/index scans per table) to the more useful Sequential Scan Tuples (i.e.,
how many rows were scanned per table) and Seq/Index Tuple Ratio (the ratio
between sequential to index scan tuples per table).

From 545cdce05d47ebbca20df8bcb6522af099ac7cec Mon Sep 17 00:00:00 2001
From: Michael Banck <michael.banck@credativ.de>

Subject: [PATCH 14/17] Dashboard: Update Connections panels.

This changes the area fill to 1 from 5 to be more in line with the other
Database-related panels. For the Connections by State panel, also add a
table-based legend, only show connections states that are present in the chosen
time range and override the colors to be more in line with their states.
