As can be seen at the bottom of http://slony.info/documentation/dropthings.html and throughout the 1.2.13 (and earlier versions) of the HTML docs, every link to toe stored procedure documentation is prefixed with 'schemadoc'. Looks like a macro gone wrong.
This is actually a bug in PostgreSQL Autodoc. If I apply the fix to autodoc described in the following commit, the labels are more appropriate. http://github.com/cbbrowne/PostgreSQL-Autodoc/commit/90b089685c3dd6fa1f863e0cfcfc51936b464bdb There may still be a problem there, but in any case, it's an upstream bug in Autodoc, which I'll (exceedingly belatedly!) bounce over to Rod Taylor.
