In neon_collector_autoscaling.jsonnet, the collector name is hardcoded to neon_collector_autoscaling. This issue manifests itself such that sql_exporter would not find the collector configuration. Signed-off-by: Tristan Partin <tristan@neon.tech>
Compute Configuration
These files are the configuration files for various other pieces of software that will be running in the compute alongside Postgres.

Adding a sql_exporter Metric
We use sql_exporter to export various metrics from Postgres. In order to add
a metric, you will need to create two files: a libsonnet and a sql file. You
will then import the libsonnet file in one of the collector files, and the
sql file will be imported in the libsonnet file.
In the event your statistic is an LSN, you may want to cast it to a float8
because Prometheus only supports floats. It's probably fine because float8 can
store integers from -2^53 to +2^53 exactly.
