locally noetherian categories and the category of quasi-coherent sheaves over a noetherian scheme
In algebraic geometry every injective quasi-coherent sheaf over a locally noetherian scheme can be written as a diret sum of some indecomposable injective qc sheves but an example is appeared in Hartshorne (Residues and duality) states that the category of qc sheves over a locally noetherian scheme may not be locally noetherian |

Is this square a push-out square?
What is the minimal condition to impose to a square to deduce that it is a pull back or a push out? |

Is this square a push-out square?
Is this square also a pull back in any abelian category? |

Thank you for your answer. But I can't justify what do you mean by $R$. You may mean $E$. Am I right? |
