+ * nailed catalog.

+ * CAUTION:  There is a GRANT in system_views.sql to grant public select
+ * access on all columns except subconninfo.  When you add a new column
+ * here, be sure to update that (or, if the new column is not to be publicly
+ * readable, update associated comments and catalogs.sgml instead).
