Description

For the function
http://doc.madlib.net/latest/group__grp__summary.html

For a table with the following column:
depdelay | double precision |

gpuser=> select madlib.summary('faa.otp_r', 'faa.otp_summary1', 'DepDelay');

results in the following error:

ERROR: ZeroDivisionError: float division (plpython.c:4648)
CONTEXT: Traceback (most recent call last):
PL/Python function "summary", line 25, in 
get_distinct, get_quartiles, ntile_array, how_many_mfv, get_estimates)
PL/Python function "summary", line 77, in summary
PL/Python function "summary", line 382, in run
PL/Python function "summary"

Don't think this should throw this error.
