Just to clarify, since Jim was responding to my comment, my thought was
*not* to use SQL commands inside initdb, but rather to use PG to create
the source files that we have today in our tree, which wouldn't slow
down initdb at all.

No, they aren't, but having the data in a table in PG, with a way to
easily export to the format needed by BKI, would make bulk updates much
easier..
