Subject [jira] [Created] (HAWQ-980) hawq does not handle guc value with space properly
Date Thu, 04 Aug 2016 11:49:20 GMT
Paul Guo created HAWQ-980:
-----------------------------

             Summary: hawq does not handle guc value with space properly
                 Key: HAWQ-980
                 URL: https://issues.apache.org/jira/browse/HAWQ-980
             Project: Apache HAWQ
          Issue Type: Bug
            Reporter: Paul Guo
            Assignee: Lei Chang


1. Set guc value with space in "alter database" could lead subsequent query fails.

e.g.
  alter database test_db set datestyle to 'postgres, MDY';
  select * from test_table;

One example of the error output is:
ERROR:  Error dispatching to seg0 localhost:40000: connection pointer is NULL
> DETAIL:
> Master unable to connect to seg0 localhost:40000: FATAL:  invalid command-line arguments
for server process
> HINT:  Try "postgres --help" for more information.

2. Currently hawq dispatch code addOneOption() removes all spaces for each guc value string.
This is wrong since space in guc value could be meaningful.
