Hi Alper,

The Quill extension to HTCondor is no longer supported or tested as of 
HTCondor v8.4 and beyond, thus I am not surprised you are having 
difficulty.  I updated the Quill wiki page to try and drive this point 
home, apologies if this was not clearly stated.

Out of curiosity, what is your interest in using Quill, i.e. what 
problem are you hoping that Quill will solve?  Most folks who used it 
back in the day were interested in reducing load on the condor_schedd 
(submit machines); these days, however, a single condor_schedd is able 
to scale to tens of thousands of active jobs and thus the primary 
motivation for setting up Quill/PostgreSQL has been removed.

Another Quill motivation from yesteryear was web portals wanted to 
interface with HTCondor via a SQL-style interface.  If that is your use 
case, I'd suggest either using the HTCondor Python API, or perhaps 
HTCondor DBQ. HTCondor DBQ is a Perl module that provides a relational 
database interface to submit HTCondor jobs, and monitor their progress 
as they are executed. The user submits work to the system by inserting a 
row into a database table. The user can query the HTCondor DBQ tables to 
monitor the progress of their work. See
  https://htcondor-wiki.cs.wisc.edu/index.cgi/wiki?p=HtcondorDbq

Hope the above helps
Todd
