Description
template0 and template1 DBs are monitored by the exporter despite DB discovery is enabled and they are added to exclude:
Exporter version:
v0.8.0
Service configuration:
EnvironmentFile=/etc/default/postgresql_exporter
Environment variables:
DATA_SOURCE_NAME="user=postgres host=/var/run/postgresql/ sslmode=disable"
PG_EXPORTER_AUTO_DISCOVER_DATABASES=true
FLAGS="--web.listen-address=:9187 --log.level=warn --exclude-databases=template0,template1"
Expected behavior:
Exclude template0 and template1 from metrics
Actual behavior:
template0 and template1 are still among metrics

Research direction
Start by reproducing the issue with the reported v0.8.0 configuration and enabled automatic database discovery, then trace how --exclude-databases is applied during discovery. Done means template0 and template1 no longer appear in the exporter’s metrics while other discovered databases remain monitored.
