Our application is using typeorm version 0.3.16 against a Postgres database, and we maintain our DB schema in TypeScript migrations. These are getting executed successfully by the ORM framework against the 'real' Postgres db.
We are using pg-mem version 2.6.9 to create some unit and integration tests for our application.
Our test code executes the following function definition:
We have recently renamed a column in one of our tables and hit the following issue.
Scenario 1: No renaming, inserting into the existing table schema, table has no primary key::
CREATE TABLE test("id" uuid NOT NULL DEFAULT uuid_generate_v4(), "col" character varying);
INSERT INTO test(id, col) VALUES (DEFAULT, '1'), (DEFAULT, '2') RETURNING "id";
Result: execution is successful.
Scenario 2: No renaming, inserting into the existing table schema, table has primary key constraint:
CREATE TABLE test("id" uuid NOT NULL DEFAULT uuid_generate_v4(), "col" character varying, CONSTRAINT "PK" PRIMARY KEY ("id"));
INSERT INTO test(id, col) VALUES (DEFAULT, '1'), (DEFAULT, '2') RETURNING "id";
Result: execution is successful.
Scenario 3: Renaming a column, and then inserting into the new table schema, table has no primary key:
CREATE TABLE test("id" uuid NOT NULL DEFAULT uuid_generate_v4(), "col" character varying);
ALTER TABLE test RENAME COLUMN "col" TO "newcol";
INSERT INTO test(id, newcol) VALUES (DEFAULT, '1'), (DEFAULT, '2') RETURNING "id";
Result: execution is successful.
Scenario 4: Renaming a column, and then inserting into the new table schema, table has primary key constraint:
CREATE TABLE test("id" uuid NOT NULL DEFAULT uuid_generate_v4(), "col" character varying, CONSTRAINT "PK" PRIMARY KEY ("id"));
ALTER TABLE test RENAME COLUMN "col" TO "newcol";
INSERT INTO test(id, newcol) VALUES (DEFAULT, '1'), (DEFAULT, '2') RETURNING "id";
Result:
Error: Corrupted alias
💥 This is a nasty error, which was unexpected by pg-mem. Also known "a bug" 😁 Please file an issue !
*️⃣ Reconsituted failed SQL statement: INSERT INTO test (id, newcol) VALUES (( DEFAULT ), ('1')), (( DEFAULT ), ('2')) RETURNING id
