+-----------------
+* Quote schema and table names returned by CDB_QueryTables [#134](https://github.com/CartoDB/cartodb-postgresql/pull/134). Use quote_ident to quote schema and table names when necessary.
+* Fixed CDB_ColumnNames [#122](https://github.com/CartoDB/cartodb-postgresql/issues/122) and CDB_ColumnType [#130](https://github.com/CartoDB/cartodb-postgresql/issues/130) should honor regclass, returning columns for just the table in the schema and not in any other one [#131](https://github.com/CartoDB/cartodb-postgresql/pull/131).

+    ```
+    FUNCTION CDB_CartodbfyTable(destschema TEXT, reloid REGCLASS)
+    RETURNS REGCLASS
+    ```
+    - The `destschema` does not need to match the origin schema of `reloid`

+  - There are many optimizations
+  - The columns `created_at` and `updated_at` will no longer be added

+
+0.5.0 (2014-11-03)
+------------------
+* Support of raster tables for cartodbfication
+* Modified quota functions: vector tables stay the same, raster tables count as full size (as have no

+Fill given extent with a rectangular coverage

+#### Using the function
+
+Create a rectangular grid from a polygon geometry. For example, take the geometry
+
+```sql
+  ST_SetSRID(
+    ST_Envelope(
+      ST_Collect(
+        ST_MakePoint(10000000,-10000000),

+     3857)
+```
+
+We can create a grid as follows, 
+
+```sql
+SELECT CDB_RectangleGrid(
+  ST_SetSRID(
+    ST_Envelope(
+      ST_Collect(
+        ST_MakePoint(10000000,-10000000),

+* **ext** geometry. Extent to fill. Only rectangles with center point falling inside the extent (or at the lower or leftmost edge) will be emitted. The returned hexagons will have the same SRID as this extent.

+* **height** float. Height of each rectangle. Measure is in the same projection as **ext**
+* **origin** OPTIONAL geometry. Optional origin to allow for exact tiling. If omitted the origin will be 0,0. The parameter is checked for having the same SRID as the extent.

+Function to "safely" transform to webmercator. This function is most useful for rendering custom geometries using the CartoDB tiler. Often, transforming a projection like WGS84 can cause issues with extents beyond what are actually valid in webmercator, this attempts to fix those issues.
+
+#### Using the function
+
+Using a box that is nearly the full globe,
+
+```sql
+ST_SetSRID(
+  ST_Envelope(
+    ST_Collect(
+      ST_MakePoint(-180,60),
+      ST_MakePoint(180,-60)
+    )
+   ),
+   4326
+)
+```
+
+We can then convert it to a renderable webmercator geometry.
+
+```sql
+SELECT CDB_TransformToWebmercator(
+ ST_SetSRID(
+  ST_Envelope(
+    ST_Collect(
+      ST_MakePoint(-10,60),
+      ST_MakePoint(300,-60)
+    )
+   ),
+   4326
+ )
+)
+```
+
+Would give you back a single valid rectangle in webmercator. Since a longitude of 300 would convert to an unallowed webmercator coordinate, it gets clipped first. Valid extent is WGS84 (-180, -89, 180, 89)

+INTRODUCTION
+============
+
+CartoDB uses a number of custom [PLpgSQL](http://www.postgresql.org/docs/8.3/static/plpgsql.html) functions to perform a few magical things. Those functions are accessible to users on CartoDB as well, so we would like to document what they are and what they do here.

+## Spatial functions
+
+[CDB_HexagonGrid](CDB_HexagonGrid) - create hexagonal grid from extent and size
+
+[CDB_MakeHexagon](CDB_MakeHexagon) - make a hexagon with given center and side
+

+
+##### Tile based
+
+[CDB_XYZ_Extent](CDB_XYZ_Extent) - Find the extent of a tile by XYZ
+
+[CDB_XYZ_Resolution](CDB_XYZ_Resolution) - Find the pixel resolution of tiles

+
+[CDB_HeadsTailsBins](CDB_HeadsTailsBins) - Find breaks in an array of numbers using Heads/Tails method
+
+[CDB_QuantileBins](CDB_QuantileBins) - Find quantile breaks in an array of numbers

+A "cartodb" user table is a table with a well-known set of fields and a well-known set of triggers attached on. 
+
+The fields are:
+
+ - `cartodb_id`, a numerical primary key of serial type
+ - `created_at`, timestamp with timezone not null default now()
+ - `updated_at`, timestamp with timezone not null default now()
+ - `the_geom`, geometry, GiST indexed, constrained (see below)
+ - `the_geom_webmercator`, geometry, GiST indexed, constrained (see below)
+
+The values of "the_geom" and "the_geom_webmercator" must match these constraints:
+
+ - Only POINT, MULTILINE, MULTIPOLYGON types ? Maybe UNCONSTRAINED
+ - Only 2 dimensions ? Maybe UNCONSTRAINED
+ - SRID=4326 for the_geom and SRID=3857 for the_geom_webmercator
+
+The triggers are:
+
+ - `track_updates` after modifying statement updates cdb_tablemetadata
+ - `test_quota` before changing statement to forbid if overquota
+ - `test_quota_per_row` before changing row to forbod if overquota (checked on a probabilistic basis)
+ - `update_the_geom_webmercator` before insert or update row to maintain the_geom_webmercator
+ - `update_updated_at_trigger` before update row to maintain updated_at
+
+Some conversions will be attempted to perform upon cartodbfication when certain fields appear:
+
+ - `cartodb_id`: If found type TEXT will be attempted to cast
+ - `created_at`: If found type TEXT will be attempted to cast
+ - `updated_at`: If found type TEXT will be attempted to cast

+The CartoDB PostgreSQL extension is a module to load into each CartoDB user database to perform cartodb-specific security and functionality checks.
+
+# Checks
+
+No user other than the superuser should be allowed to change `statement_timeout` for the session (SET statement_timeout disallowed).
+
+User tables need to match certain structure criteria (See [[CartoDB-user-table]]) so the extension should provide a mean to enforce such structure everytime an attempt to change structure is encountered. 
+
+# Events
+
+The events we want some function to be called upon are:
+
+| event                  | arguments to handler function        | function duty                    | OK* |
+|------------------------|--------------------------------------|----------------------------------|-----|
+| SET variable           | name of variable                     | forbid changing some vars        |     |
+| RENAME table           | old and new name + oid of the table  | flush cache                      |     |
+| ADD/DROP/ALTER column  | oid of the table                     | flush cache, cartodbfy, upd meta |  Y  |
+| DISABLE/DROP trigger   | oid of table, name of trigger        | cartodbfy or forbid              |     |
+| DROP table             | oid of the table                     | flush cache and metadata         |  Y  |
+| CREATE table           | oid of the table                     | cartodby, upd metadata           |  Y  |
+| GRANT                  | oid of table, privilege, role        | flush cache, upd metadata        |
+| REVOKE                 | oid of table, privilege, role        | flush cache, upd metadata        |
+
+
+* event available by installing https://github.com/CartoDB/pg_schema_triggers
+
+At this stage we don't need more than this, but the number of events and the number of arguments passed to the handler function may expand in the future, so the extension should be written in a way to easily allow that.
+
+Some of the handler will need to act _after_ the statement is completed (CREATE TABLE, for example).
