There's not so much difference between a data INSERT and file storage.
But, as a first step, you should decide on the way you want to store
the related data. Will it be stored on a normal table row (in a bytea
field) or as a large object? If you'll use LO, then you should refer
to its documentation for related functions and examples. But if you'll
use a normal bytea column, I'd strongly encourage you to use
parameters while inserting data. This is going to save you from CPU
and RAM wasting escaping routines, plus SQL-Injection attacks. (For
further performance tweaks, you can use binary mode while transmitting
data.)

Regards.
