I completed the copyright assignment procedure, so I come back to 
propose my changes.

To avoid you browsing your mails to find the first message, I summarize 
again the changes in this mail, and attach the patch to it.

This patch adds support for :dbhost, :dbuser and :database parameters 
for SQL code blocks that uses postgresql engine. This allows to abstract 
postgresql login details instead of sending parameters in a 
psql-specific format using :cmdline argument.

I am still at your service for any comment on the code.

Regards,
Steven Rémot
