- Added the pg_lolseek function, which allows for arbitrary seeking within

  a large object, and the pg_lotell call, which can be used to find the
  current file offset for a large object (Submitted by: Adam Haberlach
  <adam@newsnipple.com>).
@- Added the pg_lolseek and pg_lotell functions (Derick)
