It was already discussed here. The conclusion was: BAD IDEA. No
way to work efficiently with different DBs using the same
approach. Btw., I don't have any problems providing support for
MySQL, PostgreSQL and Oracle from one OCaml application - but the
abstraction is on a higher level then JDBC-like interfaces
provides.

No way. Too much differences in the way how DBs returns the
query results (e.g., consider the postgresql asyncronous
messages). More layers converting values would just give much
more overhead, without any significiant advantages.
