PostgreSQL psql: Schema Navigation Quick Reference

A short refresher for navigating PostgreSQL databases, schemas, and objects from the psql command line.

Schemas

List all schemas:

\dn
Enter fullscreen mode Exit fullscreen mode

List schemas with additional information:

\dn+
Enter fullscreen mode Exit fullscreen mode

Check the current schema search path:

SHOW search_path;
Enter fullscreen mode Exit fullscreen mode

Set the schema search path for the current session:

SET search_path TO schema_name;
Enter fullscreen mode Exit fullscreen mode

Databases

List databases:

\l
Enter fullscreen mode Exit fullscreen mode

Connect to another database:

\c database_name
Enter fullscreen mode Exit fullscreen mode

Show the current connection:

\conninfo
Enter fullscreen mode Exit fullscreen mode

Show the current database:

SELECT current_database();
Enter fullscreen mode Exit fullscreen mode

Show the current user:

SELECT current_user;
Enter fullscreen mode Exit fullscreen mode

Tables

List tables in the current schema:

\dt
Enter fullscreen mode Exit fullscreen mode

List tables in a specific schema:

\dt schema_name.*
Enter fullscreen mode Exit fullscreen mode

List tables across all schemas:

\dt *.*
Enter fullscreen mode Exit fullscreen mode

List tables with additional information:

\dt+
Enter fullscreen mode Exit fullscreen mode

Show the structure of a table:

\d table_name
Enter fullscreen mode Exit fullscreen mode

Show detailed information about a table:

\d+ table_name
Enter fullscreen mode Exit fullscreen mode

Other Database Objects

List views:

\dv
Enter fullscreen mode Exit fullscreen mode

List functions:

\df
Enter fullscreen mode Exit fullscreen mode

List indexes:

\di

List sequences:

These commands cover most of the basic navigation and object discovery you'll need when working with PostgreSQL from the command line.
