Postgres Single Quote Escaping Breaking Migrations

Bug description

Prisma Migrate does not handle double single quotes (‘’) in a schema. This is an issues because Postgres uses double single quotes (‘’) to escape a single quote (') in a JSONB default.

How to reproduce

1. Create a schema.prisma file or pull from a db with the following schema (this is from an introspection on my specific DB; Notice the two quotes (‘’)):

birthday_award                        Json?    @default("{\"amount\": 250, \"status\": false, \"message\": \"HAPPY BIRTHDAY, @receiver_username!! Here''s +amount to celebrate!\", \"visibility\": \"Publicly Visible\"}")

1. Run npx prisma migrate dev --name init
2. Notice the error.

Expected behavior

The migration to successfully apply.

The error given:

Update: I assumed that the original table should say Here's and modified the generated SQL to match that:

CREATE TABLE "Foo" (
    "id" INTEGER NOT NULL,
    "bar" JSONB DEFAULT '{"message": "This message includes a quote: Here''s it!"}',

    CONSTRAINT "Foo_pkey" PRIMARY KEY ("id")
);

When you create a new row of that table, you get a Here's via the default value. But when you db pull, it will write the schema we have above, and it will then on migrate dev again create broken SQL instead of the SQL of the original table.

Thank you, this is the correct assumption and the correct bug. Thank you for looking into it.

Another bump here. We could really use this for our migrations. Also, workarounds are acceptable.
