My understanding is that GetPointerv was initially introduced with OpenGL 1.1, removed with OpenGL 3.1 Core and readded with OpenGL 4.3 Core. However it is only displayed on the help page as supported in OpenGL 4.3+.
In addition, under Notes "It is available in the compatibility profile for all GL versions". I don't know whether this includes the OpenGL versions before the introductions of Core and Compat profile, however in case it does, this statement is also incorrect, as OpenGL 1.0 did not include GetPointerv.
