Incident brief

WITH CHECK OPTION violation

Writing through a view defined WITH CHECK OPTION fails when the new or updated row would fall outside the view's WHERE condition; the row must remain visible through the view.

What lands in your log

ERROR: new row violates check option for view "active_accounts"

Reproduced on PostgreSQL 18.4Verified 2026-07-24 (isolated lab, PostgreSQL 18.4)Verified against PostgreSQL 18.4 in an isolated lab environment

In 10 seconds

What triggers it: Define a view with a WHERE filter and WITH CHECK OPTION, then INSERT or UPDATE a row that does not satisfy the filter.
Fix: Write values that satisfy the view's WHERE condition, so the row stays visible through the view.
Proof: Reproduced on PostgreSQL 18.4 → An INSERT through the view reproduces SQLSTATE 44000; a row outside the view's filter is rejected with a DETAIL showing the failing values.

Fix

What to do right now

Application-level steps for this error.

Write values that satisfy the view's WHERE condition, so the row stays visible through the view.
Or write to the base table directly if the row legitimately falls outside the view.

Fix SQL

-- Insert a row that satisfies the view's condition.
INSERT INTO active_accounts (status) VALUES ('active');

For this error

See this error live on the server

Run these against the affected instance to confirm the diagnosis before you act.

Find the view's CHECK OPTION and underlying predicate; the rejected row is not visible through that view definition.

Views enforcing CHECK OPTION

Show local/cascaded check option and the view SQL.

SELECT table_schema, table_name, check_option, view_definition
FROM information_schema.views
WHERE check_option <> 'NONE'
ORDER BY table_schema, table_name;

Reproduce & verify

A real, single-session PostgreSQL reproduction

A literal transcript of SQL run against a live PostgreSQL instance in an isolated lab. The commands below are exactly what was executed.

1Define a view with a WHERE filter and WITH CHECK OPTION, then INSERT or UPDATE a row that does not satisfy the filter.
2PostgreSQL applies the view's condition to the new row.
3Because the row would not be visible through the view, the write aborts with SQLSTATE 44000.

An app inserted a 'closed' account through a view that only shows active accounts, and the CHECK OPTION blocked the invisible row.

Schema setup

CREATE TABLE accounts_base(status text);
CREATE VIEW active_accounts AS SELECT * FROM accounts_base WHERE status = 'active' WITH CHECK OPTION;

Writing a row outside the view's filter

INSERT INTO active_accounts (status) VALUES ('closed');

The session continues normally

SELECT 'ok' AS session_after_error;

What PostgreSQL actually returned

Schema setup output

CREATE TABLE
CREATE VIEW

Writing a row outside the view's filter output

ERROR:  new row violates check option for view "active_accounts"
DETAIL:  Failing row contains (closed).

The session continues normally output

 session_after_error 
---------------------
 ok
