when i run without the ANALIZE the output is:

pba=# EXPLAIN ( TIMING, BUFFERS) SELECT idprodxintegrar FROM _gc_tb a LEFT  join _gc_cat b on ( b.arama <@ a.arama  and a.arama <@ b.arama );
ERROR:  la opción BUFFERS de EXPLAIN requiere ANALYZE
pba=# EXPLAIN ( TIMING) SELECT idprodxintegrar FROM _gc_tb a LEFT  join _gc_cat b on ( b.arama <@ a.arama  and a.arama <@ b.arama );
ERROR:  la opción TIMING de EXPLAIN requiere ANALYZE



if i run only with EXPLAIN the output is:
