The Doctorate of Philosophy (Ph.D. ) is the highest doctorate. However, there are some doctorates granted in the United Kingdom called Higher Doctorates which are awarded for a successful academic career and considerable research.

In summary the Ph.D. is not only the highest doctorate among the "real" academic doctorates but also ranks much higher than puffed up pseudo doctorates such as the M.D. and J.D. in terms of scholarship and academics.
A postdoctoral degree is a degree earned after obtaining a doctorate where the doctorate is a prerequisite necessary to pursue the degree. This is seen primarily with professional doctorates. For example, most dentists in the U.S. have a DDS degree, which stands for doctor of dental surgery. It is a professional doctorate, but there are at least two available postdoctoral degrees including a Ph.D., which is a research doctorate. Another example is in law. Attorneys in the U.S. graduate law school with a Juris Doctorate, or JD. There are two available postdoctoral degrees. One is the LLM, and the second is the JSD (or SJD). The SJD is the equivalent of a Ph.D. Put simply, sometimes a 'professional' doctorate is a prerequisite for obtaining a second 'research' doctorate.
