[bug,postgres] pq-result-error-message returns ""...

I'm following the examples in the info documentation, and have created the example database, etc. Everything works fine, up until I get to "libpq Lisp Symbols and DataTypes", pq-result-error-message, and C-x C-e those examples. The first one blonks like it says it should, and prints: fatal error [ERROR: parser: parse error at or near "-" ] ... in the minibuffer. The second statement, however, returns "" rather than the expected string. I found that the variable R is not being set - That is, the error message in the minibuffer is coming from inside of the `pq-exec', and that's never returning to the `setq' to set R.
