Hi,

it seems, the postgres\_exporter delivered with pmm2-client (I have v2.10.0) does not support SCRAM-SHA-256 authentication method agains PostgreSQL Databases. Are there plans to have this method included?

pmm-agent[42262]: #033[36mINFO#033[0m[2020-09-21T10:43:42.763+00:00] time=“2020-09-21T10:43:42Z” level=error msg=“Error opening connection to database (postgres://pmm\_user:PASSWORD\_REMOVED@127.0.0.1:5432/postgres?connect\_timeout=1&sslmode=disable): pq: unknown authentication response: 10” source=“postgres\_exporter.go:1396” #033[36magentID#033[0m=/agent\_id/5473e304-8001-4ae7-a440-4ab00df7fb21 #033[36mcomponent#033[0m=agent-process #033[36mtype#033[0m=postgres\_exporter

Hi, @bjoernvb

Unfortunately SCRAM-SHA-256 support is spotty in clients connecting to postgres:

[python](https://slack-redir.net/link?url=https%3A%2F%2Fpasslib.readthedocs.io%2Fen%2Fstable%2Flib%2Fpasslib.hash.scram.html)

- implementation reference

[java](https://slack-redir.net/link?url=https%3A%2F%2Fwww.postgresql.org%2Fabout%2Fnews%2F1825%2F)

- implementation reference

Maybe in the future it will be implemented, but now it is impossible to say when.
