Hi, I am not sure whether these are new for 9.4 but they're worth looking at anyway: Valgrind was run with: --trace-children=yes --quiet \ --track-origins=yes --leak-check=no \ --read-var-info=yes \ --suppressions=/home/andres/src/postgresql/src/tools/valgrind.supp \ <postgres with options> All seem to be due btree_bit's fault and they seem to have a common origin. Didn't look at code.
