Radim Marek: The hidden cost of PostgreSQL arrays

Jimmy Angelakos: pg_statviz 0.9 released with new features
Happy New Year! I'm excited to announce release 0.9 of pg_statviz, the minimalist extension and utility pair for time series analysis and visualization of PostgreSQL internal statistics.
This is a significant feature release that expands the scope of analysis to include several new modules and a visualization update:
Esther Minano: Optimizing data throughput for Postgres snapshots with batch size auto-tuning
Floor Drees: Updating CloudNativePG's documentation
