Follow
PostgresConf South Africa

Justin Harvey

PostgresConf South Africa 2019

https://postgresconf.org/conferences/...

My talk is a beginners guide to using and understanding EXPLAIN ANALYZE.

This will include understanding: INDEX SCAN VS. BITMAP SCAN VS. SEQUENTIAL SCAN (BASICS) Btree vs GIN vs GiST vs SPGiST vs BRIN vs HASH Costs and actual times

This is for unskilled and new PostgreSQL users.
