Monitoring query latency, wait events, and locks in PostgreSQL helps identify and diagnose performance bottlenecks. Here’s a guide on how to monitor these aspects: Here’s a sample query to gather information about locks, wait events, […]
PostgreSQL execution plans provide information on how the database intends to execute a given query. Understanding execution plans is crucial to identify performance issues and optimize query performance. Here are some of the things to […]
SORT operations and the ordered property of index scans are important aspects of PostgreSQL query optimization and performance tuning. In this explanation, we will explore these concepts in detail with real data examples. SORT operations […]
Clustered and non-clustered indexes are important database indexing techniques used in PostgreSQL to improve the performance of SQL queries. In this answer, we will explain the implementation of clustered and non-clustered indexes in PostgreSQL, provide […]
Parameterized queries and bind parameters are important concepts in PostgreSQL (and other database systems) that can help improve performance, security, and maintainability of SQL queries. Parameterized queries are SQL queries where placeholders are used for […]
Regular vacuuming and reindexing of PostgreSQL infrastructure is essential for optimal performance because it helps to reclaim disk space, reduce index bloat, and maintain data consistency. Here are some of the reasons why regular vacuuming […]
Redo and Undo are essential components of any database management system, including PostgreSQL. Redo and Undo are used to maintain the consistency and durability of the database by enabling the recovery of transactions in the […]
Partial indexes in PostgreSQL allow you to create an index on a subset of a table’s rows that meet a certain condition. This can be useful for improving query performance on a subset of data […]
PostgreSQL 16 introduced several enhancements to the JSON data type constructor, which is used to create JSON data structures in the database. Some of the key enhancements include: These enhancements to the JSON data type […]
PostgreSQL’s JSONB data type allows you to store arbitrary JSON data in a structured format. This can be useful for storing data that does not fit neatly into a traditional relational database schema, such as […]
