+# Suppress complaints about stuff leaked during function cache loading.
+# Both the PL/pgSQL and SQL-function parsing processes generate some cruft
+# within the function's cache context, which doesn't seem worth the trouble
+# to get rid of.  Moreover, there are cases where CachedFunction structs
+# are intentionally leaked because we're unsure if any fn_extra pointers
+# remain.
