Podjetje Postgres Professional je objavilo izid Postgres Pro Enterprise za 1C 18.4.1<\/a>. Posodobitev je usmerjena na velike in\u0161talacije \"1C\", kjer se podatkovna baza redno soo\u010da s kompleksnimi poizvedbami, \u0161tevilnimi povezavami, za\u010dasnimi tabelami, poro\u010dili in rednimi operacijami. V uradnih opombah k izdaji<\/a> je navedeno, da Nova razli\u010dica temelji na PostgreSQL 18.4 in Postgres Pro Enterprise 18.3.2.<\/p>\n

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

Ena od glavnih sprememb je mo\u017enost uporabe za\u010dasnih tabel, za\u010dasnih zaporedij in za\u010dasnih pogledov na stre\u017eniku za vro\u010do rezervacijo. Funkcija se aktivira s parametrom enable_standby_temp_tables<\/a> skupaj z enable_temp_memory_catalog in hot_standby. Prakti\u010dni pomen je enostaven: te\u017eka poro\u010dila in procesi ETL se lahko prenesejo na stre\u017enik za rezervno, ne da bi obremenjevali glavni vozli\u0161\u010de.<\/p>\n

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

Za na\u010drtovalnik poizvedb je dodan mehanizem enable_join_predicate_pushdown<\/a>. Ta omogo\u010da potiskanje pogojev povezovanja iz zunanje poizvedbe v vgrajene podpoizvedbe, da lahko optimizator izbere bolj\u0161i na\u010drt izvajanja. Prav tako je bila pospe\u0161ena ocena selektivnosti za velike sezname MCV in izbolj\u0161ano delovanje z omejenimi izbirami preko planner_upper_limit_estimation; to bi moralo biti opazno v tipi\u010dnih scenarijih \"1C\", vklju\u010dno s zapiranjem obdobja in izdelavo poro\u010dil.<\/p>\n

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

Posodobljena je tudi orodja za odpornost na napake. Vgrajena re\u0161itev BiHA<\/a> je pre\u0161la na razli\u010dico 1.8: ve\u010dplastna geografska razporeditev in odpornost proti katastrofam ve\u010d ne veljata za eksperimentalni, povezave med vozli\u0161\u010di pa je mogo\u010de za\u0161\u010dititi s SSL certifikati. V Proxima je uvedena prilagodljiva obremenitvena porazdelitev, ki upo\u0161teva CPU, pomnilnik in diskovni vhod-izhod, ter podpora za ve\u010d povezovalnih naslovov -- IPv4, IPv6 in Unix-sokete.<\/p>\n

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

V izdaji so vklju\u010dena tudi nova orodja in raz\u0161iritve. pgpro_iheap<\/a> dodaja tabelarni dostopni na\u010din iheap, ki je zasnovan za pospe\u0161itev zaporednega skeniranja, medtem ko pgpro_temp_stats<\/a> samodejno zbira statistiko o za\u010dasnih tabelah, da na\u010drtovalnik ne deluje na slepo. Za skrbnike je dodano orodje pgpro_validate<\/a>, ki preverja celovitost datotek, indeksov, tabel, sistemskih katalogov in pravic dostopa v primeru Postgres Pro.<\/p>\n

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

Ker Postgres Pro Enterprise 18.4.1 temelji na PostgreSQL 18.4<\/a>, vklju\u010duje tudi popravke iz apstrimanja PostgreSQL. Za nadgradnjo znotraj iste glavne razli\u010dice zadostuje namestitev novega izida v trenutni imenik, a pri spremembi ABI razvijalci priporo\u010dajo posodobitev prilo\u017eenih raz\u0161iritev ali ponovno sestavljanje tretjih strank.<\/p>\n
