Spolo\u010dnos\u0165 Postgres Professional ozn\u00e1mila uvedenie Postgres Pro Enterprise pre 1C 18.4.1<\/a>. Aktualiz\u00e1cia je zameran\u00e1 na ve\u013ek\u00e9 in\u0161tal\u00e1cie \u201e1C\u201c, kde datab\u00e1za pravidelne \u010del\u00ed zlo\u017eit\u00fdm dotazom, mno\u017estvu pripojen\u00ed, do\u010dasn\u00fdm tabu\u013ek\u00e1m, spr\u00e1vam a pravideln\u00fdm oper\u00e1ci\u00e1m. V ofici\u00e1lnych pozn\u00e1mkach k vydaniu<\/a> je uveden\u00e9, \u017ee nov\u00e1 verzia je zalo\u017een\u00e1 na PostgreSQL 18.4 a Postgres Pro Enterprise 18.3.2.<\/p>\n

Jednou z hlavn\u00fdch zmien je mo\u017enos\u0165 pou\u017e\u00edva\u0165 do\u010dasn\u00e9 tabu\u013eky, do\u010dasn\u00e9 sekvencie a do\u010dasn\u00e9 poh\u013eady na serveri hotov\u00e9ho z\u00e1lohovania. Funkcia sa aktivuje pomocou parametra enable_standby_temp_tables<\/a> spolu s enable_temp_memory_catalog a hot_standby. Praktick\u00fd v\u00fdznam je jednoduch\u00fd: n\u00e1ro\u010dn\u00e9 spr\u00e1vy a ETL procesy je mo\u017en\u00e9 presun\u00fa\u0165 na standby server, bez za\u0165a\u017eovania hlavn\u00e9ho uzla.<\/p>\n

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

Pre pl\u00e1nova\u010d dotazov bol pridan\u00fd mechanizmus enable_join_predicate_pushdown<\/a>. Umo\u017e\u0148uje pren\u00e1\u0161a\u0165 podmienky spojenia z vonkaj\u0161ieho dotazu do vnoren\u00fdch poddotazov, aby optimaliz\u00e1tor mohol zvoli\u0165 v\u00fdhodnej\u0161\u00ed pl\u00e1n vykon\u00e1vania. Rovnako bola ur\u00fdchlen\u00e1 oce\u0148ovanie selektivity pre ve\u013ek\u00e9 zoznamy MCV a zlep\u0161en\u00e1 pr\u00e1ca s obmedzen\u00fdmi v\u00fdbermi cez planner_upper_limit_estimation; to by malo by\u0165 zjavn\u00e9 v typick\u00fdch scen\u00e1roch \u201e1C\u201c, vr\u00e1tane uzatv\u00e1rania obdob\u00ed a vytv\u00e1rania spr\u00e1v.<\/p>\n

Boli aktualizovan\u00e9 aj prostriedky odolnosti vo\u010di chyb\u00e1m. Vstavan\u00e9 rie\u0161enie BiHA<\/a> pre\u0161lo na verziu 1.8: viac\u00farov\u0148ov\u00e1 geo-distrib\u00facia a odolnos\u0165 vo\u010di katastrof\u00e1m sa u\u017e pova\u017euj\u00fa za stabiln\u00e9, a slu\u017eobn\u00e9 spojenia medzi uzlami je mo\u017en\u00e9 zabezpe\u010di\u0165 SSL certifik\u00e1tmi. V Proxima sa objavila adapt\u00edvna vyva\u017eovanie, ktor\u00e9 zoh\u013ead\u0148uje CPU, pam\u00e4\u0165 a diskov\u00fd I\/O, ako aj podpora viacer\u00fdch pripojovac\u00edch adries \u2014 IPv4, IPv6 a Unix-soketov.<\/p>\n

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

V release sa tie\u017e objavili nov\u00e9 n\u00e1stroje a roz\u0161\u00edrenia. pgpro_iheap<\/a> prid\u00e1va tabu\u013ekov\u00fa met\u00f3du pr\u00edstupu iheap, navrhnut\u00fa na ur\u00fdchlenie sekven\u010dn\u00e9ho skenovania, a pgpro_temp_stats<\/a> automaticky zhroma\u017e\u010fuje \u0161tatistiky o do\u010dasn\u00fdch tabu\u013ek\u00e1ch, aby pl\u00e1nova\u010d nepracoval naslepo. Pre administr\u00e1torov bola pridan\u00e1 utilita pgpro_validate<\/a>, ktor\u00e1 kontroluje integritu s\u00faborov, indexov, tabuliek, syst\u00e9mov\u00fdch katal\u00f3gov a pr\u00e1v na pr\u00edstup v in\u0161tancii Postgres Pro.<\/p>\n

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

Ke\u010f\u017ee Postgres Pro Enterprise 18.4.1 je zalo\u017een\u00fd na PostgreSQL 18.4<\/a>, obsahuje aj opravy z upstreamu PostgreSQL. Pre aktualiz\u00e1ciu v r\u00e1mci tej istej hlavnej verzie sta\u010d\u00ed nain\u0161talova\u0165 nov\u00fa verziu do aktu\u00e1lneho adres\u00e1ra, ale pri zmene ABI v\u00fdvoj\u00e1ri odpor\u00fa\u010daj\u00fa aktualizova\u0165 dod\u00e1van\u00e9 roz\u0161\u00edrenia alebo prekompilova\u0165 extern\u00e9.<\/p>\n
