Rectify parameter count for translate() function

[docktermj]

In Pull Request #79

In init-postgresql.py there is a change to the translate() function from old line 648 to new line 712 that reduces the parameters from 2 parameters to 1 parameter.

However, on new lines 785 - 797 the code still has the call to translate() using 2 parameters.

This produces the following error:

Traceback (most recent call last):
