Yes, but again. In my own psql usage, it goes like this: "this is a simple and easy SQL, most of it was cut/paste anyway .... what could possibly go wrong .... ups". But it goes wrong in less then every 20th or 100th time, less then once in a few months. So i don't realy feel like pushing somebody into a development effort, that woud just slightly enhance psql comfort of usage. I most certainly want even be cooking any macros, as .... I would forget to use it when it could be of some help.
My comment on this thread was mearly to object, that a request to allow maintaining transaction state despite syntax error is "obviusly wrong".

And this is a really good point - although I do know my schemas and I can choose appropriate moment for long hand-opened transation, mistakes happen (well, this whole thread is about mistakes :)
Additionally, I would point out that the times I have gotten into trouble with long-running transactions delaying other users it has been functioning queries which updated lots of rows unexpectedly slowly, not syntax errors ;-)
