+ <span class="productname">PostgreSQL</span> has a <em class="firstterm">large object</em>
+ facility, which provides stream-style access to user data that is stored
+ in a special large-object structure. Streaming access is useful
+ when working with data values that are too large to manipulate
+ conveniently as a whole.
+ </p><p>
+ This chapter describes the implementation and the programming and
+ query language interfaces to <span class="productname">PostgreSQL</span>
+ large object data. We use the <span class="application">libpq</span> C
+ library for the examples in this chapter, but most programming
+ interfaces native to <span class="productname">PostgreSQL</span> support
+ equivalent functionality. Other interfaces might use the large
+ object interface internally to provide generic support for large
+ values. This is not described here.
