![]() One effective approach to gathering Valgrind memcheck instrumentation while running the regression tests is outlined here. However, it's not clear that "fix" will hide all instances The simplest answer is to set autovacuum = off in nf while using Valgrind. If you're prepared to recompile Valgrind, apply the one-line patch shown there. If you observe core dumps in autovacuum while running under Valgrind on x86_64 hardware, it's probably a known bug in valgrind 3.8.1 and earlier You should normally use MEMORY_CONTEXT_CHECKING with USE_VALGRIND instrumentation of repalloc() is inferior without it. See src/include/pg_config_manual.h for full details of how to build Postgres with support for Valgrind memcheck instrumentation. ![]() ![]() Postgres supports Valgrind memcheck directly - it is possible to include "client requests" in the memory allocator, providing detection of many additional memory others that would otherwise not be detected in vanilla builds.
