While you would like to characterize the question as being
one of mere aggregation (because you would like the GPL to
not affect a combined work), that is incorrect, not least
because the OP is not doing any aggregation with GPLed code
at all.
The OP is writing an application which interoperates with a
database schema created by a GPLed program. While, in fact,
his application does not need to be released under the GPL,
that is because his program contains no GPLed code.
