Hi Kevin,
From the PG documentation (section 5.8 - inheritance):
http://www.postgresql.org/docs/current/static/ddl-inherit.html
"A serious limitation of the inheritance feature is that indexes (including
unique constraints) and foreign key constraints only apply to single tables,
not to their inheritance children. This is true on both the referencing and
referenced sides of a foreign key constraint."
So there's no "best place", there's only one place for the indexes and
constraints - which is the table(s) that contain the data, which would usually
be the individual partition tables.
(This caveat seems to be absent from the Partitioning documentation (section
5.9))
Cheers,
~Hrishi
