Inheritance is certainly very useful/convenient especially for "table
partitioning" (though not the same as in Oracle) and for modeling
supertype-subtype stuffs.

The only drawback I see is that the implementation is still lacking in
several area, e.g. no hierarchy-wide unique constraints, so you'll have
to resort to triggers. And there doesn't seem to be many people using it
at the moment, so if there were a bug then it might get fixed less quickly.

Ironically, the last sentence could be argued as the reason *to* use
inheritance in Postgres, to get more people using and testing it. :-)
