PostgreSQLConnection
Tamaño total de la caché del índice primario en bytes. Contiene índices primarios cargados bajo demanda cuando
primary_key_lazy_load=1 y use_primary_key_cache=1. Las asignaciones se alojan en la arena de jemalloc dedicada a la caché (jemalloc.cache_arena.*). NUNCA se solapa con system.parts.primary_key_bytes_in_memory[_allocated] — el índice de una parte está o bien en esta caché (contabilizado aquí) o bien en la propia parte (contabilizado allí); nunca en ambas. Para obtener la memoria total del índice primario en todas las partes, suma ambos.
