multiple postgres exporter for a DB clusters

[deechella]

Proposal

Having multiple postgres DB in our RDS DB clusters. As of now, we have installed a helm chart of prometheus postgres exporter to scrape the metrics for a single postgress database. Is there any other possibility of adding the another postgres exporter for monitoring the rest of Postgres database in our clusters? Suggest any better approach on monitoring the postgres databases in the DB clusters using prometheus postgres exporter

##Requirement:
Need to configure the remaining postgres databases in our clusters withthe prometheus postgres exporters.Already configured one
“Nice to have” is not a good use case. :)

Rather than directly configure databases servers in the exporter, I want to add multi-target exporter support. This will allow you to have a single exporter for multiple RDS instances.
