* Bacula Catalog Database routines specific to PostgreSQL
* Dan Langille, December 2003
* based upon work done by Kern Sibbald, March 2000
*
- * Major rewrite by Marco van Wieringen, January 2010 for catalog refactoring.
+ * Note: at one point, this file was changed to class based by a certain
+ * programmer, and other than "wrapping" in a class, which is a trivial
+ * change for a C++ programmer, nothing substantial was done, yet all the
+ * code was recommitted under this programmer's name. Consequently, we
+ * undo those changes here. Unfortunately, it is too difficult to put
+ * back the original author's name (Dan Langille) on the parts he wrote.
