Re: async fast-path calls?

hi,

i workarounded this by using PQsendQuery with eg. "select lowrite($1,$2)".
while it seems to work, i wonder if it's ok to use these functions this way,
given that only some of large object server-side functions are documented
in http://www.postgresql.org/docs/9.0/interactive/lo-funcs.html.
