Why load python script is failing with error "Sys has no argument 'argv'"?

When the library is used with embedded Python (e.g. Postgres extension written in C calling Python, like Multicorn), sys.argv is not defined, which makes the library misbehave.

Workaround : Assign a empty string to the sys.argv value as given below while importing the same and it should work.

import sys

if not hasattr(sys, 'argv'):
    sys.argv  = ['']
