Comment(by strk):

 I've been indeed thinking that ST_Simplify could be extended to accept the
 algorithm name as a parameter. It could work as long as the same parameter
 type (a single float?) could be used by all signatures.

 ST_Visvalingam also has the advantage of allowing both "tag-only" and
 "tag-and-drop" behaviors not to conflict with the name (ie: why should a
 "SetEffectiveArea" function drop vertices?).

 Whatever you decide to do, please provide unit testing and documentation
 too
