all. I use "pg_basebackup" to make slave, but the master has too large

Unfortunately not, there have been several discussions about being
able to define a blacklist of paths when taking a backup but nothing
has showed up in the code tree. For log files, there is a trick
though: you can define log_directory with an absolute path pointing
out of PGDATA so those logs won't be included in base backups.

Can I modify "sendDir" function to skip the log_direction (default is "pg_log") ?

the sendDir function is :
static int64
sendDir(char *path, int basepathlen, bool sizeonly, List *tablespaces)
{
DIR *dir;
struct dirent *de;
charpathbuf[MAXPGPATH];
struct stat statbuf;
int64size = 0;

dir = AllocateDir(path);
while ((de = ReadDir(dir, path)) != NULL)
{
/* Skip special stuff */
              if (strcmp(de->d_name, ".") == 0 || strcmp(de->d_name, "..") == 0)  
continue;
.......
--if (strcmp(de->d_name, ".") == 0 || strcmp(de->d_name, "..") == 0) 
++ if (strcmp(de->d_name, ".") == 0 || strcmp(de->d_name, "..") == 0 || strcmp(de->d_name, "pg_log"))    

Is there something wrong ?

Thanks,

Of course you can patch your own version of the backend. That will
just not be supported by community if there are bugs in your patches.
You are looking at Log_directory by the way.
