Description

Queries related to temp will send request to RPS, asking the privilege of schema "pg_temp_XXX", like this:

./hawq-2017-02-13_142852.csv:2017-02-13 14:29:29.718445 CST,"linw","postgres",p71787,th-1324481600,"[local]",,2017-02-13 14:29:01 CST, 8477,con13,cmd3,seg-1,,,x8477,sx1,"DEBUG3","00000","send json request to ranger : { ""requestId"": ""3"", ""user"": ""linw"", ""client Ip"": ""127.0.0.1"", ""context"": ""select * from temp1;"", ""access"": [ { ""resource"":

{ ""database"": ""postgres"", ""schema"": "" pg_temp_13"", ""table"": ""temp1"" }

, ""privileges"": [ ""select"" ] } ] }",,,,,,"select * from temp1;",0,,"rangerrest.c",454,

In order to better control, for pg_temp_XX schema and objects in that schema, we should fall back these checks to catalog without sending requests to RPS.
