Hi Prashant,
I have not used the Postgres exporter, but judging by the code at
https://github.com/prometheus-community/postgres_exporter/blob/dcf498e709b121eb1ff2e193f66c8ff2d4611b58/cmd/postgres_exporter/postgres_exporter.go#L663-L703,
the "pg_exporter_last_scrape_error" metric having a value of 1 means that
the exporter was unable to connect to the Postgres backend. It also logs
the specific error message, so you should be able to see the exact backend
connection error reason in your exporter's logs.
Kind regards,
Julius
