Entre ellos, se han solucionado problemas que, en raras circunstancias, pod\u00edan provocar la corrupci\u00f3n de \u00edndices al modificar cadenas HOT (heap-only tuple) durante la operaci\u00f3n VACUUM o al ejecutar la operaci\u00f3n REINDEX CONCURRENTLY en \u00edndices de tablas que utilizan el mecanismo de almacenamiento TOAST.     <\/p>\n<p>Se han corregido los cierres inesperados durante la ejecuci\u00f3n de ALTER STATISTICS y al extraer datos con tipos multirango. Se han solucionado errores en el planificador de consultas que provocaban resultados incorrectos. Se han eliminado fugas de memoria al actualizar \u00edndices por expresiones y al realizar la operaci\u00f3n 'REASSIGN OWNED BY' sobre un gran n\u00famero de objetos. Se ha garantizado la generaci\u00f3n de estad\u00edsticas avanzadas para tablas segmentadas.     <\/p>\n<p>Tambi\u00e9n se puede se\u00f1alar el lanzamiento de la herramienta reshape, que permite realizar actualizaciones complejas en el esquema de datos en PostgreSQL sin detener el funcionamiento, lo que normalmente requerir\u00eda cambios manuales y detener temporalmente los servicios que utilizan la base de datos. La herramienta permite la transici\u00f3n de un viejo esquema de datos a uno nuevo sin bloqueos prolongados y sin interrumpir el ciclo de procesamiento de consultas. La herramienta crea autom\u00e1ticamente vistas de tablas, con las que las aplicaciones contin\u00faan trabajando durante la migraci\u00f3n del esquema de datos, y tambi\u00e9n configura desencadenadores que traducen las operaciones de adici\u00f3n y eliminaci\u00f3n de datos entre el viejo y el nuevo esquema.     <\/p>\n<p>As\u00ed, al utilizar reshape durante la migraci\u00f3n, el viejo y el nuevo esquema permanecen accesibles al mismo tiempo y las aplicaciones se pueden transferir gradualmente al nuevo esquema sin detener su funcionamiento (en grandes infraestructuras se pueden reemplazar los controladores antiguos por nuevos de manera progresiva). Una vez que se ha completado la transici\u00f3n de las aplicaciones al nuevo esquema, las vistas y desencadenadores creados para mantener la compatibilidad con el viejo esquema se eliminan. En caso de detectar problemas con las aplicaciones durante la migraci\u00f3n, se puede revertir el cambio de esquema y volver al estado anterior.<br \/>\n<br \/>Fuente: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=56677\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u0421\u0444\u043e\u0440\u043c\u0438\u0440\u043e\u0432\u0430\u043d\u044b \u043a\u043e\u0440\u0440\u0435\u043a\u0442\u0438\u0440\u0443\u044e\u0449\u0438\u0435 \u043e\u0431\u043d\u043e\u0432\u043b\u0435\u043d\u0438\u044f \u0434\u043b\u044f \u0432\u0441\u0435\u0445 \u043f\u043e\u0434\u0434\u0435\u0440\u0436\u0438\u0432\u0430\u0435\u043c\u044b\u0445 \u0432\u0435\u0442\u043e\u043a PostgreSQL: 14.2, 13.6, 12.10, 11.15 \u0438 10.20, \u0432 \u043a\u043e\u0442\u043e\u0440\u044b\u0445 \u0438\u0441\u043f\u0440\u0430\u0432\u043b\u0435\u043d\u043e 55 \u043e\u0448\u0438\u0431\u043e\u043a, \u0432\u044b\u044f\u0432\u043b\u0435\u043d\u043d\u044b\u0445 \u0437\u0430 \u043f\u043e\u0441\u043b\u0435\u0434\u043d\u0438\u0435 \u0442\u0440\u0438 \u043c\u0435\u0441\u044f\u0446\u0430. \u0412 \u0442\u043e\u043c \u0447\u0438\u0441\u043b\u0435 \u0443\u0441\u0442\u0440\u0430\u043d\u0435\u043d\u044b \u043f\u0440\u043e\u0431\u043b\u0435\u043c\u044b, \u043f\u0440\u0438\u0432\u043e\u0434\u0438\u0432\u0448\u0438\u0435 \u043f\u0440\u0438 \u0440\u0435\u0434\u043a\u043e\u043c \u0441\u0442\u0435\u0447\u0435\u043d\u0438\u0438 \u043e\u0431\u0441\u0442\u043e\u044f\u0442\u0435\u043b\u044c\u0441\u0442\u0432 \u043a \u043f\u043e\u0432\u0440\u0435\u0436\u0434\u0435\u043d\u0438\u044e \u0438\u043d\u0434\u0435\u043a\u0441\u043e\u0432 \u043f\u0440\u0438 \u0438\u0437\u043c\u0435\u043d\u0435\u043d\u0438\u0438 \u0446\u0435\u043f\u043e\u0447\u0435\u043a HOT (heap-only tuple) \u0432\u043e \u0432\u0440\u0435\u043c\u044f \u0432\u044b\u043f\u043e\u043b\u043d\u0435\u043d\u0438\u044f \u043e\u043f\u0435\u0440\u0430\u0446\u0438\u0438 VACUUM \u0438\u043b\u0438 \u043f\u0440\u0438 \u0432\u044b\u043f\u043e\u043b\u043d\u0435\u043d\u0438\u0438 \u043e\u043f\u0435\u0440\u0430\u0446\u0438\u0438 REINDEX CONCURRENTLY \u0434\u043b\u044f [&hellip;]<\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[702],"tags":[],"class_list":["post-103298","post","type-post","status-publish","format-standard","hentry","category-news"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 5.0.2 -
