Fix two bugs in funcs.source that made the tutorial script fail.
Make a LOT of fixes to syscat.source to: * Set search_path properly (and reset it) * Add schema name to all results * Add schema name to ORDER BY first * Make checks for user-defined objects match reality * format_type all type names * Respect attisdropped * Change !~ to 'not like' since it's more standard Christopher Kings-Lynne
