Announcing pg_statviz, a minimalist extension and utility pair for time series analysis and visualization of PostgreSQL internal statistics. This talk will be the official announcement of pg_statviz, a new extension and utility pair created for snapshotting PostgreSQL's cumulative and dynamic statistics, and performing time series analysis on them. The accompanying utility can produce visualizations for selected time ranges on the stored stats snapshots, enabling the user to track PostgreSQL performance over time and potentially perform tuning or troubleshooting.
