    In JRuby you can’t use the pg gem as you would in regular Ruby, so you can’t use it’s large object support.

    However you do have access to PgJDBC, so you can use the large object features offered by PgJDBC, same as you would from Java directly. See:

    • http://jdbc.postgresql.org/documentation/91/largeobjects.html
    • http://jdbc.postgresql.org/documentation/91/binary-data.html#binary-data-example

    This should work much the same in JRuby as in regular Java.
