Drop support for feferred misspelling in

PostgreSqlPlatform::getAdvancedForeignKeyOptionsSQL()

UPGRADE.md

 # Upgrade to 3.0
 
+## BC BREAK PostgreSqlPlatform ForeignKeyConstraint support for `feferred` misspelling removed
+
+`PostgreSqlPlatform::getAdvancedForeignKeyOptionsSQL()` had a typo in it in 2.x. Both the option name
+`feferred` and `deferred` were supported in `2.x` but the misspelling was removed in 3.x.
+
 ## BC BREAK `AbstractSchemaManager::extractDoctrineTypeFromComment()` changed, `::removeDoctrineTypeFromComment()` removed
 
 `AbstractSchemaManager::extractDoctrineTypeFromComment()` made `protected`. It takes the comment by reference, removes the type annotation from it and returns the extracted Doctrine type.
