Yes, I have experience analyzing query plans in PostgreSQL. To obtain a query plan, the command used is:
EXPLAIN ANALYZE <your_query>;
It returns a detailed execution plan with information about time, number of rows, and used indexes.
When analyzing, I pay attention to:
- Use of indexes or full table scans (Seq Scan).
- Estimated number of rows at each stage.
- Execution time of each step.
- Presence of bottlenecks, such as sorts or hash joins.
Based on this, the query can be optimized by adding indexes, rewriting conditions, or changing the data structure.
