 ## Transformations
 The following functions produce new array values from existing ones.

+
+Generate a series of values, from `start` to `stop` with a given `step` size
+
+```sql_template
+`generate_series(<start>, <stop> [, <step>])`
+```
+
+If `step` is not specified, the default step size of `1` will be used.
+When `step` is positive, zero rows are returned if `start` is greater
+than `stop`. Conversely, when `step` is negative, zero rows are returned
+if `start` is less than `stop`. Zero rows are also returned for `NULL`

+## `unnest` {#unnest}
+
+The `unnest` function expands the elements from an array:

+    Mon
+    Tue
+    Wed
+    Thu
+    Fri
+    (5 rows)
+
+`unnest` can also be called with multiple array paramters (potentially of different data types). In this case, the arrays are expanded pairwise. If the arrays are not all the same length then the shorter ones are padded with NULLs.
+
+    SELECT * FROM unnest(
+        ARRAY['Mon','Tue','Wed','Thu','Fri'],
+        ARRAY[1,2,3,4,5,6,7]
