Definition — PostgreSQL performance: understand queries before adding indexes

What it is, why it matters

Investigate slow database operations using representative data, execution plans and index trade-offs instead of guessing from application symptoms.

Key concepts

  • PostgreSQL
  • Database performance
  • SQL
  • Backend

In short : Measure the query and workload first. An index is a targeted trade-off, not a universal fix for every slow endpoint.
