I've been fooling with catalog entries here and I've obviously done something
wrong. But I'm a bit frustrated trying to debug initdb. Because of the way it
starts up the database in a separate process I'm finding it really hard to
connect to the database and get a backtrace. And the debugging log is being
spectacularly unhelpful in not telling me where the problem is.

Are there any tricks people have for debugging bootstrapping processing? I
just need to know what index it's trying to build here and that should be
enough to point me in the right direction:

creating template1 database in /var/tmp/db7/base/1 ... FATAL: could not create unique index
DETAIL: Table contains duplicated values.
