ST_AsSVG — Returns a Geometry in SVG path data given a geometry or geography object.
text ST_AsSVG(geometry geom, integer rel=0, integer maxdecimaldigits=15
text ST_AsSVG(geography geog, integer rel=0, integer maxdecimaldigits=15
Return the geometry as Scalar Vector Graphics (SVG) path data. Use 1 as second argument to have the path data implemented in terms of relative moves, the default (or 0) uses absolute moves. Third argument may be used to reduce the maximum number of decimal digits used in output (defaults to 15). Point geometries will be rendered as cx/cy when 'rel' arg is 0, x/y when 'rel' is 1. Multipoint geometries are delimited by commas (","), GeometryCollection geometries are delimited by semicolons (";").
