BC Break	no

Summary

Since doctrine/dbal 3.2.0, regular comparison is deprecated in favor of platform-aware-schema comparison: https://www.doctrine-project.org/2021/11/26/dbal-3.2.0.html

This should fix a number of false-positive and false-negative issues.

This involves changing this piece of code:

migrations/lib/Doctrine/Migrations/Generator/DiffGenerator.php

Lines 95 to 107 in 1967775

	$up = $this->migrationSqlGenerator->generate(
	$fromSchema->getMigrateToSql($toSchema, $this->platform),
	$formatted,
	$lineLength,
	$checkDbPlatform
	);
	$down = $this->migrationSqlGenerator->generate(
	$fromSchema->getMigrateFromSql($toSchema, $this->platform),
	$formatted,
	$lineLength,
	$checkDbPlatform
	);

as well as

migrations/lib/Doctrine/Migrations/Provider/DBALSchemaDiffProvider.php

Lines 46 to 49 in 1967775

	public function getSqlDiffToMigrate(Schema $fromSchema, Schema $toSchema): array
	{
	return $fromSchema->getMigrateToSql($toSchema, $this->platform);
	}
