Ankit Singhal commented on PHOENIX-2835:
----------------------------------------

bq. How about adding an example of OFFSET usage and a description here?
Yes, I'll add the usage on Grammer page too( there is already one usage example 
in paged.html in another patch)

bq. Can you include info on the config param you need to set to enable these 
commands?
Yes, I'll add reference to configuration here.

bq. I don't see anything on upgrade utility here - maybe it's in a different 
patch?
I didn't find any page for upgrade utility so I added the FAQ "How to move 
existing table with schema to namespace?". Probably can be later moved to 
namespace feature page.

+### <a id="map_table_namespace"/>How to move existing table with schema to 
namespace?
+**Pre-requisite:** you need 4.8 or higher version to map table to a namespae. 
To enable namespace mapping in configuration, see [tuning.html](tuning.html)
+
+For kerberized environment, run with the user who have sufficient 
permissiont("admin") to create a namespace.
+
+Table will be mapped to namespace of name "schema_name" only , Currently we 
don't support migrating existing table to different schema or namespace.
+
+Usage example:
+
+Move table('table_name') to namespace of name 'schema_name'
+
+    $  bin/psql.py <zookeeper> -m <schema_name>.<table_name>
