v0.65.0

• Google Cloud SQL: Support IAM Authentication
  • This allows monitoring of Google Cloud SQL databases using the existing
    db_use_iam_auth / DB_USE_IAM_AUTH setting: If enabled, the collector
    fetches a short-lived token for logging into the database instance from the
    GCP API, instead of using a hardcoded password in the collector
    configuration file
  • To set this up, see our updated Google Cloud SQL setup
    documentation
• Start collecting and report pg_stat_statements_info stats
  • This makes it easier to track down some pg_stat_statements-related
    problems
• Support monitoring non-Heroku databases with Heroku-hosted collector
• Follow symlinks when tracking storage stats for data directory
  • This fixes storage statistics accounting for data directories symlinked
    to other partitions
• Fix pg_hint_plan handling for collector-driven Query Tuning workflow
• Fix errors when collecting stats about frequently-locked partitions
• Fix receiving logs through syslog
  • This was inadvertently broken by the log parsing changes in v0.58.0
• Avoid log parsing error when database connection cannot be established
  • This was only a secondary problem, but the stack trace in the logs could
    make it harder to track down the root cause
• Sign built Go binaries for macOS
  • Due to security enhancements in newer macOS versions, unsigned Go
    binaries may hang when built and executed locally; signing makes it
    easier to debug the collector on macOS
• Update Go version to 1.23
• Update Dockerfile alpine base image to 3.21
