 EDB Wait States is a tool for analyzing performance and tuning by allowing the collection and querying of wait event data. Wait events, introduced in PostgreSQL 9.6, are recorded alongside other session activity and provide a snapshot of whether a session is waiting for I/O, CPU, IPC, locks, or timeouts. Snapshots of this information are gathered by the EDB Wait States background worker (BGW) at regular intervals.
