large obejcts

Hi,
we are pl/pgsql as the procedural language for clinet interface.
and we need to create some large objects within pl/pgsql. I did
not
get any clue  about how to create large objects and access them
within
pl/pgsql, not from 'c'
language interface. I don't know whether postgresql has the
provision
to create large objects in pl/pgsql procedures and functions at
all.
If any body has an idea about it , please help me. I want to know
whether it is possible or not to create it.
thanks
chava
