• Self-hosted: Ignore additional file system types that are not important
• Fix helper process when using systemd service
  • This unfortunately requires us to remove the "NoNewPrivileges" mode, since
    we intentionally use a setuid binary (pganalyze-collector-helper) to be
    able to discover the data directory as well as determine the size
    of the WAL directory
• Increase systemd service memory limit to 1GB
  • We've previously limited this to 256MB for all use cases, which is too
    small when monitoring multiple systems
• Security: Lock down permissions for /etc/pganalyze-collector.conf
  • Previously this was world-readable, which may make credentials accessible
    to more system users than intended
  • Upgrading the packages will also apply this fix retroactively
