Only if you change that function. It doesn't currently do anything special to run the *right* pg_config.
The patch I sent takes the view that once the install_path has been sanity checked and the *right* pg_config executed,
relyingon the environment's path variables thereafter is safe. But that means the initial pg_config execution is
uniquein not being able to rely on the path. There really isn't enough motivation for changing TestLib, I don't think,
becausesubsequent calls to pg_config don't need to be paranoid, just the first call.
