Will be done in pgScript-1.0-beta-2.

Indeed, I am using virtual methods. Is there any reasons why you
compiled with -fno-rtti ? Do I have to use wxWidgets RTTI capabilities
instead of C++ built-in capabilities?

Will fix that in the next patch.

I will look deeper at this problem tomorrow.

Right, it is the same feedback as Guillaume and I am currently working
on that. Once again it will be included in the next patch.

Weird, as the previous problem I need to look deeper at that in the
next following days.

About the documentation, I thought about adding information about the
pgScript button in the Query page and a link to the (possibly
reformated) syntax reference. About this syntax reference, how did you
find it? Was it clear?

Thank you for your feedback, it is really helpful!

Best regards,
Mickael
