I ran the query extractor on the acs-tcl package and commited a bunch of .xql files. It's possible that I broke a few things. As far as the use of site-nodes-procs.xql and site-nodes-procs-postgresql.xql, it's my understannding that queries that will work with both oracle and postgresql should go in the site-nodes-procs.xql file, and queries that are specific to postgresql go into site-nodes-procs-postgresql.xql. Likewise, queries that are specific to oracle go into site-nodes-procs-oracle.xql.
