Tom Lane e549722a8b Get rid of the rather fuzzily defined FlattenedSubLink node type in favor of ... making pull_up_sublinks() construct a full-blown JoinExpr tree representation of IN/EXISTS SubLinks that it is able to convert to semi or anti joins. This makes pull_up_sublinks() a shade more complex, but the gain in semantic clarity is worth it. I still have more to do in this area to address the previously-discussed problems, but this commit in itself fixes at least one bug in HEAD, as shown by added regression test case.		2009-02-25 03:30:38 +00:00
