A Guide to PostgreSQL Alternatives for the 'DESCRIBE' Statement

PostgreSQL lacks a direct 'DESCRIBE' statement, a feature familiar to MySQL users for inspecting table structures. This piece outlines alternatives in PostgreSQL to achieve similar results.

Here are three examples of PostgreSQL DESCRIBE alternatives:

Command Line with psql:

  • Use: \\d <table_name> for basic details; \\d+ <table_name> for extended information.

  • Advantages: Comprehensive details including constraints and indexes.

  • Drawbacks: CLI environment may be daunting for some users.

Information Schema Query:

  • Use: SELECT column_name, data_type FROM information_schema.columns WHERE table_name = '<table_name>';

  • Advantages: Direct and straightforward.

  • Drawbacks: Provides less detail, lacking info on indexes and keys.

Database Client (DbVisualizer)

  • Use: Navigate through DbVisualizer’s graphical interface after setup.

  • Advantages: In-depth and intuitive; suitable for all user levels.

  • Drawbacks: Requires initial configuration.
