## AI overview

This article presents unconventional PostgreSQL optimization techniques. It explains how constraint exclusion can use check constraints to avoid scanning a table for impossible conditions, while noting that enabling it broadly can add planning overhead; partition pruning is enabled by default for partitioned tables.

## Source excerpt

When it comes to database optimization, developers often reach for the same old tools: rewrite the query slightly differently, slap an index on a column, denormalize, analyze, vacuum, cluster, repeat. Conventional techniques are effective, but sometimes being creative can really pay off!
