conn
The handle of the connection.
descriptor
A descriptor for the large object from pg_lo_open.
offset
The new seek position in bytes.
whence
Specified from where to calculate the new seek position:
SEEK_CUR
(from current position),
SEEK_END
(from end), or

The current zero-based byte offset in the large object, after the seek is complete. This is identical to the value which would be returned by pg_lo_tell.
