I realize that this kind of feature-based testing is generally considered a best practice, but the problem is we're unlikely to do it consistently. If we put a version number in there, people will be able to test for whatever they want. Then again, why would pg_config.h be absent? -- Robert Haas EDB: http://www.enterprisedb.com
