The question is still valid, though it's better put in your words - do we want to refactor the existing compiler or write a separate one ?
So, for now I went with the path of custom compiler and current executor.
I attached current version of the patch. I don't expect this to get committed or anything, but I'd like other eyes to take a look at it. What it does: Adds laninline Oid which points to function handling inline code (aka anonymous code block). Adds DO $$some code$$ [ LANGUAGE lanname ] syntax which sends the source code to that laninline function of the specified language (or language set by default_do_language guc). There is implementation for plpgsql with simpler compiler which still creates function struct for the executor (I believe there is no harm in adjusting executor later, when current one works, just does unnecessary stuff). There is doc and a simple regression test for plpgsql implementation. -- Regards Petr Jelinek (PJMODOS)
