Labels "Arbitrary labels to add to each metric scraped from this database"

[qrkop]

n the example configuration for multiple databases, we have:

Arbitrary labels to add to each metric scraped from this database

labels:

label_name1: label_value1

label_name2: label_value2

Is this feature already supported? I’m asking because when I run it, I get the following error:
level=ERROR source=main.go:110 msg="unable to load metrics configuration" error="yaml: unmarshal errors:\n line 49: field labels not found in type collector.DatabaseConfig"
