I'm trying to efficiently allow conversion of R objects to PostgreSQL

is marked attribute_hidden. Is there some other externally available
interface that I can use?
R_Serialize is in Rinternals.h. R_serialize is a wrapper using
connections, and connections do not have a public API.
OK, thanks.
Do note the comments in ?serialize: 'persistent' storage of objects in
an experimental format is somewhat contradictory.
Good point -- I'll put a suitable warning in my documentation. The
typical use case people describe is more of a "materialized view" than
it is primary storage, so I think this is still very useful.
Thank you for your response.
Joe
