The case in question was not one of the child table being in a different
partition (do you mean schema?), although that arrangement was
considered and rejected for other reasons during data base design. In
this implementation, a function called for a table constraint was in a
different schema. The function so called was defined in the public
scheme because it is a generic function that can be used by different
applications, and some tables are relevant only to specific applications
and so have there own, application-specific schema -- but they still can
make use of shared definitions, i.e., this particular function, which
are defined in the public schema.
