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

Subject: [PATCH] ob-sql.el: Enhance postgresql support
* lisp/ob-sql.el: Add support for :dbhost, :dbuser and :database
parameters in sql code blocks for postgresql engine.
Before this patch, it was necessary to use :cmdline parameter to
specify host, user and database different the the default ones. Now,
this can be done using parameters that are independents of the engine
used.
This is not trivial (and not recommended) to pass password as a
command line argument to psql, so :dbpassword is not supported.

I used mysql parameters handling code as a template for writing my
patch, so it suffered from the same problems. I added a second patch
that renames `dbstring-mysql' to `org-babel-sql-dbstring-mysql' and that
uses `delq' instead of `remq' in its implementation. I did some basic
tests to ensure I didn't break anything.

Subject: [PATCH 2/2] ob-sql.el: Clean mysql parameters generation
* lisp/ob-sql.el (dbstring-mysql): Rename function and tweak a bit its
implementation
(org-babel-execute:sql): Use new function name
Prefix `dbstring-mysql' function with the namespace org-babel-sql to
avoid name collisions.
Also replace the call to `remq' by `delq' because it is a bit more
efficient, and also to be consistent with
`org-babel-sql-dbstring-postgresql'.
