St_linefromtext
WebPointFromText. ST_MakePoint is perhaps in terms of speed the fastest way of creating a PostGIS geometry and on tests I have done, can be as much as 5 to 10 times faster. The downside of MakePoint is that it is not defined in the OGC spec so its not quite as portable across other spatial databases as is ST_GeomFromText and PointFromText. http://www.jet-almost-lover.cn/Article/Detail/41791

WebIf from_index_name is not specified, then create from base index by default. The columns in the rollup table must be existing columns in from_index. In properties, user can specify the storage format. See CREATE TABLE for details.

It is slower than ST_GeomFromText since it adds an additional validation step. This method implements the OGC Simple Features Implementation Specification for SQL 1.1. s3.2.6.2.
