I'm occasionally seeing calls to pg_database_size() fail with ERROR: could not stat file "/var/lib/pgsql/data/base/16404/1738343": No such file or directory
So far I haven't noticed any other problems that might be related to this error. This database frequently uses temporary tables so I'm wondering if the error might be due to a race condition in db_dir_size(), which does the following: while ((direntry = ReadDir(dirdesc, path)) != NULL) { struct stat fst; if (strcmp(direntry->d_name, ".") == 0 || strcmp(direntry->d_name, "..") == 0) continue; snprintf(filename, MAXPGPATH, "%s/%s", path, direntry->d_name); if (stat(filename, &fst) < 0) ereport(ERROR, (errcode_for_file_access(), errmsg("could not stat file \"%s\": %m", filename))); dirsize += fst.st_size; } I'm wondering if the code should check for ENOENT if stat() fails and either skip this entry silently under the assumption that the file had been deleted since the call to ReadDir(), or issue a warning without failing. -- Michael Fuhr ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
