Postgres 13 su instalaci=C3=B3n es standalone, es decir cai completamente con la configuraci=C3=B3n de default, solo algunos parametros= que permiten la conexi=C3=B3n remota. La de postgres 18 si tiene varias herrami= entas externas como pgbouncer, herrimestas de metricas, como pgbouncer_exporter, postgres_exporter y node_exporter. Mi error exporadico en postgres 13 y Postgres 18 mucho m=C3=A1s frecuente en ambas es el siguiente: ERROR. cloud not open shared memory segment "/PostgreSQL. 1634730188": No such file or directory Ya he investigado cambiado algunos par=C3=A1metros de Postgres pero no logro resolverlo. Podran apoyarme en la soluci=C3=B3n, ahora pienso que es del la= do del sitema operativo.
