BUenas noches Alvaro
Mil gracias por la respuesta, actualice la versión de PostgreSQL 9.5 al
ultimo release disponible (9.5.23) y repeti el ejercicio con el mismo
resultado :-(
bash-4.2$ /opt/test/PostgreSQL/9.5/bin/psql -U postgres -p 6432 postgres
psql (9.5.23)
Type "help" for help.
postgres=# checkpoint;
CHECKPOINT
