I have successfully installed 8.3.5 as a fresh install on a Redhat 4.5 machine. Now I try to upgrade another Redhat 4.5 machine with an existing 8.2.4 install and the "make check" fails all tests. When I look at the results file for each type being tested I see the same error indicating that there is an undefined symbol: pg_valid_server_encoding_id and the test does not get run. Any ideas on what I might be missing or have to change? Thanks much.
