Hiroshi-san,

We tested it, examined the logs and can report that the problem is fixed
in the snapshot we downloaded this morning. Because so much of our work
hinges on the psqlODBC driver right now, we especially appreciate the
quick turnaround. Thank so much for the help.

Yay for open source! Boo bugs.
