I am sending a review of this patch:

1. This patch introduce location in DefElement node, and inject ParserState
to SQL commands, where ParserState was not used. It allows to show the
position of an error. This patch is not small, but almost changes are

2. There are no problems with patching, compiling, tests - all tests passed.

3. There is not any new functionality, so new tests and new documentation
is not necessary.

I'll mark this patch as ready for commiter.
