v0.30.0

• Track local replication lag in bytes
• RDS: Handle end of log files correctly
• High-frequency query collection: Avoid race condition, run in parallel
  • This also resolves a memory leak in the collector that was causing
    increased memory usage over time for systems that have a lot of
    pg_stat_statements query texts (causing the full snapshot to take
    more than a minute, which triggered the race condition)
