[Gnumed-devel] use of PG inheritance in GNUmed

A quick question: in general terms, how is PostgreSQL inheritance used
in GNUmed? I've been looking carefully at this feature of PG, and am a
bit confused by it, because column (definitions) are inherited by the
child tables from the parent tables, but rows are inherited by the
parents from the child table. In other words, the inheritance of columns
and rows operate in opposite directions, which doesn't seem very useful
to me - or at least it isn't for my purposes (unrelated to GNUmed). Does
this characteristic of the inheritance cause problems for GNUmed, or is
it an advantage.
