- Caveats

-
- The following caveats apply to partitioned tables:
-
-
-
- There is currently no way to verify that all of the
- CHECK constraints are mutually
- exclusive. Care is required by the database designer.
-
-
-
-
-
- There is currently no simple way to specify that rows must not be
- inserted into the master table. A CHECK (false)
- constraint on the master table would be inherited by all child
- tables, so that cannot be used for this purpose. One possibility is
- to set up an ON INSERT> trigger on the master table that
- always raises an error. (Alternatively, such a trigger could be
- used to redirect the data into the proper child table, instead of
- using a set of rules as suggested above.)
