I have so big big data (like about 60 Gb.) and it seems to have much unnecessary pseudo nodes.
I would like to remove them using PostGIS or QGIS without simplifying or changing its original shape (Simplification might helpful though it changes the original shape and this is not what I want... also, ArMap DataReviewer is not going to be helpful or GT Tools such as ArcMap Addin)
What function names should I look into? I have polygons and polylines that need to be worked done.
this might be the closest answer that i am looking for but this is related to lines and i need to delete them :(
examples of Pseudo Nodes in Polyline is illustrated below. (and the second picture, i need to apply this to polygons too)

so, the definition of Pseudo Nodes here is unnecessary nodes in a shape. Also, with or without the pseudo nodes, the shape will still remain the same.
For instance, straight line only needs end nodes (2 nodes) but somehow there is a couple of extra nodes on the line (for some reason. maybe editting error), i would like to remove them.
