hi, does any postgres extractor support iam authentication?

I don't think it does. Do you mean something like https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/rds/client/generate_db_auth_token.html?

@Edgar Ramírez (Arch.dev) exactly. i guess a work around would be to create that token and then set the .env variables to that token

Yeah, that'd work I created https://github.com/MeltanoLabs/tap-postgres/issues/346 to keep track.
