what gives: SELECT INVALID SELECT STATEMENT TO FORCE ODBC DRIVER TO UNPREPARED STATE

Server logs below.  Notice how an error raised in a connection to the
proj02u20411 database forces the transaction in the instrumentation
database to rollback.
Can anyone explain why connections that as far as PG should conserned
are unrelated are actually interferring with one another?
