Looking at the docs, it seems that SQL Developer has a GUI. SQL Mode,
like all inferior modes, needs to communicate with the subprocess using
stdin and stdout. I assume this will not work.

The same applies here. SQL Mode uses stdin and stdout to communicate.
Using a vendor-specific library would require a totally different
approach.

There is an alternative, however:
http://www.emacswiki.org/emacs/PostgreSQL has "Code by EricMarsden for a
socket-level elisp interface to PostgreSQL."
