Incident brief

Schema does not exist

A CREATE TABLE statement referenced a schema name that doesn't exist yet. PostgreSQL rejected it instead of creating the schema implicitly.

ERROR: schema "batch9_orders_schema" does not exist

Reproduced on PostgreSQL 16.14Verified 2026-07-16 (Docker lab, PostgreSQL 16.14)Verified against PostgreSQL 16.14 in an isolated lab environment

In 10 seconds

What triggers it
Run CREATE TABLE against an explicitly qualified schema name that has not been created.
Fix
Run CREATE SCHEMA first, then create the table inside it.
Proof
Reproduced on PostgreSQL 16.14 → CREATE TABLE against an explicitly qualified, nonexistent schema name was rejected with SQLSTATE 3F000.

Fix

What to do right now

Application-level steps for this error.

  • Run CREATE SCHEMA first, then create the table inside it.
  • Don't assume adding the schema name to search_path is enough on its own, see the premium counterexample for what search_path actually does with a nonexistent entry.
Fix SQL
CREATE SCHEMA batch9_orders_schema;
CREATE TABLE batch9_orders_schema.orders (id int);
