------------------------------------------------------------

Also, this problem tells us that MADlib (at least madpack) works with postgres 
via command-line tool (psql) rather than via some libpq-based driver. I see 
that you use `subprocess.Popen` in `run_query` function...
Did you consider using some Python driver to execute SQL code? I believe that 
driver would be better both in terms of performance and "clear work" (no issues 
like this one, with psql's such startup messages)

> Actually subject speaks for itself: if you place smth like "\timing on" to 
> .psqlrc (for convenience working with psql; smth that generates additional 
> output at psql's startup time), you cannot install MADlib to some Postgres DB 
> -- it reports:
> ```
> madpack.py : ERROR : Failed reading database version
> ```
