Description
In PostgreSQL, the schema search path determines the order in which schemas are checked when referencing unqualified object names. By default, if you don't specify a schema, PostgreSQL searches the schemas in a defined order to find the requested object. Understanding how to configure the search path helps in controlling database behavior, especially when dealing with multiple schemas.

What Is Schema Search Path?
The schema search path is a list of schemas that PostgreSQL uses when it searches for an object without a schema name. The search path is set to "$user", public by default, meaning PostgreSQL first looks for objects in the schema matching the current user’s name and then in the public schema.

How to View the Current Search Path?
To see the current search path in your session:

SHOW search_path;

How to Set the Schema Search Path?

You can modify the search path to control which schemas are searched first:

SET search_path TO sales, public;

Now, PostgreSQL will first look in the sales schema and then in the public schema when you reference unqualified objects.

How the Search Path Affects Object Creation?
When creating new objects, PostgreSQL will place them in the first schema in the search path unless specified otherwise. For example:

CREATE TABLE customers (
customer_id SERIAL PRIMARY KEY,
customer_name TEXT NOT NULL
);

If the sales schema is first in the search path, the customers table will be created in the sales schema.

Reverting to the Default Search Path
To revert to the default search path:

SET search_path TO public;

Why Use Schema Search Path?
✅ Controls schema precedence for object lookup
✅ Simplifies database management by setting a default schema
✅ Helps avoid naming conflicts in multi-schema environments
