  • Update to Go 1.19
  • Bugfix: Ensure relfrozenxid = 0 is tracked as full frozenxid = 0 (instead of
    adding epoch prefix)
  • Amazon RDS and Amazon Aurora: Support IAM token authentication
    • This adds a new configuration setting, db_use_iam_auth / DB_USE_IAM_AUTH.
      If enabled, the collector fetches a short-lived token for logging into the
      database instance from the AWS API, instead of using a hardcoded password
      in the collector configuration file
    • In order to use this setting, IAM authentication needs to be enabled on the
      database instance / cluster, and the pganalyze IAM policy needs to be
      extended to cover the "rds-db:connect" privilege for the pganalyze user:
      https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/UsingWithRDS.IAMDBAuth.IAMPolicy.html
  • Amazon RDS: Avoid DescribeDBInstances calls for log downloads for RDS instances
    • This should reduce issues with rate limiting on this API call in some cases
  • Amazon Aurora: Cache failures in DescribeDBClusters calls for up to 10 minutes
    • This reduces repeated calls to the AWS API when the cluster identifier is
      incorrect
  • Log parsing: Add support for timezones specified by number, such as "-03"
