Jeremy,

If you set PROJ_LIB as a system environment variable, and restarted the
postmaster or whatever the postgres daemon is called on windows, I would
have expected it to work.

By default PROJ on windows is built with C:/PROJ/NAD as the directory to
search for datum shift files.  This is determined by the PROJ_LIB_DIR
set in proj/src/makefile.vc
