    Share the same connection pool for primary and replica databases in the

    🛠 Fix the preloader when one record is fetched using after_initialize
    but not the entire colection.

    Bradley Price

    🗄 Correctly deprecate where.not working as NOR for relations.

    🗄 12a9664 deprecated where.not working as NOR, however
    doing a relation query like where.not(relation: { ... })
    🗄 wouldn't be properly deprecated and where.not would work as
    NAND instead.

    Edouard Chin

    🛠 Fix db:migrate task with multiple databases to restore the connection
    to the previous database.

    The migrate task iterates and establish a connection over each db
    resulting in the last one to be used by subsequent rake tasks.
    We should reestablish a connection to the connection that was
    established before the migrate tasks was run
