SQL access is frequently more convenient, though. Although maybe now that we've made recovery.conf use the GUC lexer we oughta continue in that vein and expose those parameters as PGC_INTERNAL GUCs rather than inventing a new function for it...
+1 for SQL access, but exposing it via pg_settings opens up the security problem as there might be sensitive info in those GUCs.
