+```sql
+SELECT CDB_GreatCircle(start_point, end_point) FROM table_name
+-- Results a line reprsenting the great circle between the two points
+```
+
+#### Arguments
+
+CDB_GreatCircle(start_point, end_point)
+
+* **start_point** ST_Point indicating the start of the line.
+* **end_point** ST_point indicating the end of the line.

+Introduction
+============
+
+This document aims at describing what cartodbfy is and what its formal requirements are, with the following goals in mind:
+
+- clarify what are the expectations of the "cartodbfycation process".
+- define an important part of what should be a stable, public API
+- allow for better testing, which should in turn...
+- ...ease modifications and increase quality of the code
+
+
+
+What is the cartodbfycation
+===========================
+
+The cartodbfycation is the process of converting an arbitrary postgres table into a valid CartoDB table, and register it in the system so that it can be used in the CartoDB editor and platform to generate maps and analysis.
+
+
+
+Valid CartoDB tables
+====================
+
+A valid CartoDB table shall meet the following conditions:
+
+- Have a ``cartodb_id`` integer column as primary key with a sequence as default value
+- Have a ``the_geom`` column of type ``Geometry`` with SRID 4326
+- Have a ``the_geom_webmercator`` column of type ``Geometry`` with SRID 3857
+- The columns ``the_geom`` and ``the_geom_webmercator`` shall be in sync
+
+Additionally, a CartoDB table can contain other columns.
+
+
+
+High level requirements
+=======================
+
+Here is a list of high level requirments for the public function ``CDB_CartodbfyTable()``:
+
+- A call to ``CDB_CartodbfyTable()`` shall modify/rewrite the table and produce a valid CartoDB table with the same name.
+- A call to ``CDB_CartodbfyTable()`` shall cause the registration of the table into the platform
+- It shall be idempotent, meaning that successive calls to ``CDB_CartodbfyTable()`` shall not produce any visible effect in the system.
+- If there's a column containing a geometry, it shall be used to generate ``the_geom`` and the ``the_geom_webmercator`` columns.
+- Exporting and re-importing the same table in CartoDB shall produce equivalent tables, with the same features associated to the same ``cartodb_id``'s.
+
+Note that there should be only one feature per row in the source table. If there's more than one, then which one is used for ``the_geom`` and ``the_geom_webmercator`` fields is not determined.
+
+
+
+Low-level requirements
+======================
+
+- If the original table contains a valid (unique and not null) ``cartodb_id`` column, it shall be used
+- If the original table contains a ``the_geom`` column or a ``the_geom_webmercator`` column in the expected projection (EPSG 4326 and EPSG 3857, respectively) they shall be used.
+- A modification of a cartodbfy'ed table shall insert or update a row in ``CDB_TableMetadata``
+- A cartodbfy'ed table shall have a ``btree`` index on ``cartodb_id``
+- A cartodbfy'ed table shall have ``gist`` indices on ``the_geom`` and ``the_geom_webmercator``
+- Cartodbfy shall deal with text columns for imports, regarding CartoDB columns
