slony issues.

I already asked this basic question on the slony mailing lists, but
they seem kinda quiet this week.

So, I've got a database with about 30,000 objects in it, and running
the setaddtable() function is taking about 30 seconds, and spinning a
CPU 100% while doing it. Any suggestions on indexes, or changing
functional costs to get this to run in a more reasonable time. I'm
adding about 600 tables and 200 sequences, and with each table taking
30 seconds it's taking about 5 hours to create a set, which is just
crazy to me. On a much slower machine but without the other 29,000 or
so objects, each table takes around 5 to 10 seconds to add, which is
still long, but not quite as long as on my production server.
