Hi.

At the moment libpq doesn't seem to support asynchronous and
non-blocking support for large objects, in the style of
PQsendQuery/PQgetResult. This makes large objects hardly suited for
single-threaded programs based on some variant of select().

According to http://www.postgresql.org/docs/9.2/static/lo-funcs.html

"There are server-side functions callable from SQL that correspond to each of

the client-side functions". Hence, you can call these functions by using

asynchronous API.
