Breaking Change Fix: PostgreSQL Dollar-Quoted Functions

Previously, SQL migrations were always split by semicolons, which broke PostgreSQL functions using dollar-quoted strings ($$...$$). This release fixes the issue by disabling statement splitting by default.

What Changed

New Configuration Option

Example:

config := amigo.Configuration{
    SplitStatements: true,  // Enable for ClickHouse
}

Annotation Reference

Examples

PostgreSQL Functions (Now Works by Default)

-- migrate:up
CREATE OR REPLACE FUNCTION uuid_generate_v7()
RETURNS uuid AS $$
BEGIN
  -- Internal semicolons no longer break the migration
  SELECT 1;
  SELECT 2;
  RETURN gen_random_uuid();
END;
$$ LANGUAGE plpgsql;

-- migrate:down
DROP FUNCTION IF EXISTS uuid_generate_v7();

ClickHouse with Protected Blocks

For ClickHouse users who need statement splitting, enable it and use annotations to protect complex statements:

config := amigo.Configuration{
    SplitStatements: true,  // Required for ClickHouse
}

-- migrate:up
CREATE TABLE foo (id UInt64) ENGINE = MergeTree();

-- amigo:statement:begin
CREATE FUNCTION myFunc AS (x) -> multiIf(
    x = 1, 'one;',
    x = 2, 'two;',
    'other'
);
-- amigo:statement:end

CREATE TABLE bar (id UInt64) ENGINE = MergeTree();

-- migrate:down
DROP TABLE bar;
DROP FUNCTION myFunc;
DROP TABLE foo;

Migration Guide

Remove active record like thing, focus on migration in go and sql, with multi database support and no extra dependencies.

Breaking change :

• better consistency, use main.go generated for the whole cli
• better support for unsuported drivers
• change config to contexts.yml, better support for multiple db with the cli

BREAKING CHANGE: migrations are now in db/migrations.

• better logging support
• possibility to migrate using schema.sql (for fresh installs)
• dump the schema via amigo schema
• dump the schema via migrate/rollback cmd (-d flag)
• update documentation

• BREAKING CHANGE: default amigo folder is now inside migrations/db
• feature: Query with auto closing of rows

refactor: better errors

BREAKING CHANGE: changing the id column to version in the table mig_schema_migrations

feature: add raw sql support

• support unknown dsn
