Fixed issue where server default compare would not work for string defaults that contained backslashes, due to mis-rendering of these values when comparing their contents.
Implemented basic server default comparison for the Oracle backend; previously, Oracle's formatting of reflected defaults prevented any matches from occurring.
Adjusted SQLite's compare server default implementation to better handle defaults with or without parens around them, from both the reflected and the local metadata side.
Adjusted SQL Server's compare server default implementation to better handle defaults with or without parens around them, from both the reflected and the local metadata side.
