1. The header comment for pass_down_bound() could mention "one or more levels of subqueries" rather than "a subquery".
Fixed
2. The first of the comments in the function body appears to have a whitespace issue that needs to be fixed manually or, better yet, addressed by pgindent.
Fixed
3. The formatting of the comment in the regression tests appears to be unlike any other comment in that same file.
A side effect of inheriting it from our branches ;-) Reworked.
4. I am pretty doubtful that "Memory: 25kB" is going to be stable enough for us to want that output memorialized in the regression ...
Fair enough. I wanted to be a bit more sophisticated in my check than looking for a single value so I worked out something that distills the explain down to the key elements.
