Apparently, their set_cachesize() function now returns an error
when Postfix sets the cache size.
This code has not changed since Postfix 2.0, more than 10 years ago:
if ((errno = db->set_cachesize(db, 0, dict_db_cache_size, 0)) != 0)
msg_fatal("set DB cache size %d: %m", dict_db_cache_size);
131072 (128 kbyte) is the Postfix default read buffer size:
berkeley_db_read_buffer_size = 131072
There is a similar parameter for writing, used in postmap.
None of this has changed since Postfix 2.0.
