I think what you're looking for is make-table-modifier, however, the
delete operation is missing somehow, I may forgot to add it. So a PR is
The modifications in mysql/postgresql/sqlite3 are different, so we have
to take care of them. Please follow the similar pattern of the
definition inside make-table-modifier.
The FPRM is still experimental and not well tested yet, but I encourage
you to report any exceptions.
BTW, you don't have to create a modifer with this contructor, the preferred way
is to create a table mapping with (map-table-from-DB rc/conn), and pass
'mod as the first argument for calling modifier.
