Is there a way to get the data size of a large object ? I would like to
be able
to read an entire large object using lo_read function. Since this
function needs
a "len" parameter as input, I have to know the size of the large
object...
Any idea ?
Thanks.

Just seek to the end, remember the return value, and seek back.
