Chapter 42.
Large Objects |
Next |
Originally, Postgres 4.2 supported three standard
implementations of large objects: as files external to Postgres, as
UNIX files managed by Postgres, and as data stored within the
Postgres database. It causes considerable confusion among users. As
a result, we only support large objects as data stored within the
Postgres database in PostgreSQL. Even though is is slower to
access, it provides stricter data integrity. For historical
reasons, this storage scheme is referred to as Inversion large
objects. (We will use Inversion and large objects interchangeably
to mean the same thing in this section.)
