You can find this in Postgresql documentation :
PostgreSQL
Prev
Chapter 44. Large Objects
Built in registered functions
There are two built-in registered functions, lo_import and lo_export which are convenient for use in SQL queries.
Here is an example of their use 

CREATE TABLE image (   name            text,   raster          oid
);

INSERT INTO image (name, raster)   VALUES ('beautiful image', lo_import('/etc/motd'));

SELECT lo_export(image.raster, "/tmp/motd") from image   WHERE name = 'beautiful image';

Emmanuel.
