Hi pgsql hacker, Recently I have been trying to understand why GUC changes will be visible even though they are done in the signal handler as part of *ProcessConfigfile* (done in some extension code). Later I have seen almost all postgresql processes/bgworkers use signal handler to set a variable *ConfigReloadPending *which will later be read in main code to process guc changes but for postmaster *ProcessConfigfile *is being called from signal handler itself which intern has memory allocation related code (non-async safe code). Is it safe to do this?
