Interesting.  To clarify, are these commands run within a single
transaction, and if not where are the transaction boundaries?

Would you run this under log_error_verbosity = verbose and post the
full postmaster log entry for the failure, especially the LOCATION
data?  (Even better would be a stack trace from the errfinish call,
but perhaps LOCATION will be enough.)
