How does St transform in PostGIS do it?
ST_Transform actually changes the coordinates of a geometry from one spatial reference system to another, while ST_SetSRID () simply changes the SRID identifier of the geometry. Requires PostGIS be compiled with Proj support. Use PostGIS_Full_Version to confirm you have proj support compiled in.
When to use Foo and other words like it?
Foo and other words like it are formally known as metasyntactic variables. It can be helpful to use metasyntactic variables when creating sample code because programmers don’t have to create unique names for each variable value. Nonsense placeholders make it easier to focus on the code’s core concept and functional goal.
When to use PostGIS _ full _ version in Proj?
Use PostGIS_Full_Version to confirm you have proj support compiled in. If using more than one transformation, it is useful to have a functional index on the commonly used transformations to take advantage of index usage. Prior to 1.3.4, this function crashes if used with geometries that contain CURVES. This is fixed in 1.3.4+
