- <para>
- <application>pg_dump</> (and by implication
- <application>pg_dumpall</>) has a few limitations which stem from
- the difficulty of reconstructing certain information from the system
- catalogs.

- <para>
- Specifically, the order in which <application>pg_dump</> writes
- the objects is not very sophisticated. This can lead to problems
- for example when functions are used as column default values. The
- only answer is to manually reorder the dump. If you created
- circular dependencies in your schema then you will have more work
- to do.
