Force an object to appear to come from a specific database
Note
DO NOT use this function to create ids to feed into fetch()!
Objects created in this way may lack vital underlying data required later.
Instead use ohvbd.ids() for this purpose.
Examples
force_db(c(1,2,3), "vt")
#> [1] 1 2 3
#> attr(,"db")
#> [1] "vt"
