A empresa Postgres Professional anunciou o lan\u00e7amento Postgres Pro Enterprise para 1C 18.4.1<\/a>. A atualiza\u00e7\u00e3o \u00e9 direcionada a grandes instala\u00e7\u00f5es de \"1C\", onde o banco de dados frequentemente enfrenta consultas complexas, m\u00faltiplas conex\u00f5es, tabelas tempor\u00e1rias, relat\u00f3rios e opera\u00e7\u00f5es regulares. Nas observa\u00e7\u00f5es oficiais sobre o lan\u00e7amento<\/a> , \u00e9 indicado que a nova vers\u00e3o \u00e9 baseada no PostgreSQL 18.4 e no Postgres Pro Enterprise 18.3.2.<\/p>\n

<\/noindex> <\/p>\n

Uma das principais mudan\u00e7as \u00e9 a possibilidade de usar tabelas tempor\u00e1rias, sequ\u00eancias tempor\u00e1rias e vistas tempor\u00e1rias no servidor de reserva quente. A fun\u00e7\u00e3o \u00e9 ativada pela op\u00e7\u00e3o enable_standby_temp_tables<\/a> junto com enable_temp_memory_catalog e hot_standby. O sentido pr\u00e1tico \u00e9 simples: relat\u00f3rios pesados e processos ETL podem ser transferidos para o servidor de reserva, sem sobrecarregar o n\u00f3 principal.<\/p>\n

<\/noindex> <\/p>\n

Para o planejador de consultas, foi adicionado o mecanismo enable_join_predicate_pushdown<\/a>. Ele permite que as condi\u00e7\u00f5es de jun\u00e7\u00e3o sejam empurradas de consultas externas para subconsultas aninhadas, para que o otimizador possa escolher um plano de execu\u00e7\u00e3o mais eficiente. Al\u00e9m disso, a avalia\u00e7\u00e3o da seletividade para grandes listas MCV foi acelerada e o trabalho com amostras limitadas foi melhorado por meio do planner_upper_limit_estimation; isso deve ser percept\u00edvel em cen\u00e1rios t\u00edpicos de \"1C\", incluindo fechamento de per\u00edodo e gera\u00e7\u00e3o de relat\u00f3rios.<\/p>\n

<\/noindex> <\/p>\n

As ferramentas de resist\u00eancia \u00e0 falha tamb\u00e9m foram atualizadas. A solu\u00e7\u00e3o integrada BiHA<\/a> passou a vers\u00e3o 1.8: a geodistribui\u00e7\u00e3o em m\u00faltiplos n\u00edveis e a resist\u00eancia a desastres n\u00e3o s\u00e3o mais consideradas experimentais, e as conex\u00f5es de servi\u00e7o entre os n\u00f3s podem ser protegidas por certificados SSL. No Proxima, foi adicionada uma balanceamento adaptativo que considera CPU, mem\u00f3ria e entrada\/sa\u00edda de disco, al\u00e9m de suporte para v\u00e1rios endere\u00e7os de conex\u00e3o \u2014 IPv4, IPv6 e sockets Unix.<\/p>\n

<\/noindex> <\/p>\n

O lan\u00e7amento tamb\u00e9m incluiu novas ferramentas e extens\u00f5es. pgpro_iheap<\/a> adiciona um m\u00e9todo de acesso tabular iheap, projetado para acelerar a varredura sequencial, enquanto pgpro_temp_stats<\/a> recolhe automaticamente estat\u00edsticas sobre tabelas tempor\u00e1rias, para que o planejador n\u00e3o atue no escuro. Para administradores, foi adicionada a ferramenta pgpro_validate<\/a>, que verifica a integridade de arquivos, \u00edndices, tabelas, cat\u00e1logos de sistema e permiss\u00f5es no inst\u00e2ncia do Postgres Pro.<\/p>\n

<\/noindex> <\/p>\n

Como o Postgres Pro Enterprise 18.4.1 \u00e9 baseado no PostgreSQL 18.4<\/a>, tamb\u00e9m inclui corre\u00e7\u00f5es do upstream do PostgreSQL. Para atualizar dentro da mesma vers\u00e3o principal, basta instalar a nova vers\u00e3o no diret\u00f3rio atual, mas ao alterar a ABI, os desenvolvedores recomendam atualizar as extens\u00f5es fornecidas ou recompilar as de terceiros.<\/p>\n
