[PERFORM] PostgreSQL overall design
Hi All, Can anyone please tell/point me where I can get the postgresql system layout (I've an interest to contribute). I would also like to know the files involved for performing each task ( for eg when doing a select operation what is exactly happening in postgres along with the files). I was wandering inside the source for a while and I couldn't get a start point to go with. Need a clarification in copydir.c file of src/port directory, In the following snippet the destination directory is created first then the source directory is read. Suppose if I don't have permission to read the source, even then the destination directory would be created. I just want to know whether there is any reason for doing so? if (mkdir(todir, S_IRUSR | S_IWUSR | S_IXUSR) != 0) ereport(ERROR, (errcode_for_file_access(), errmsg("could not create directory \"%s\": %m", todir))); xldir = AllocateDir(fromdir); if (xldir == NULL) ereport(ERROR, (errcode_for_file_access(), errmsg("could not open directory \"%s\": %m", fromdir))); -- with thanks & regards,S.GnanavelSatyam Computer Services Ltd.
