Postgres views and materialized views are useful tools for organizing and viewing results from commonly used queries. Views simplify the process of running complex queries, while materialized views offer faster result retrieval with the trade-off of having stale data. Materialized views can be particularly helpful in cases where query execution times become unbearable or exceed service level agreements. However, it's essential to optimize slow-running queries even when using materialized views and ensure that the frequency of refreshing materialized views aligns with their specific use-cases.
