Voprosy `ekspluatacii
1.4) Suschestvuyut li versii perenesennye ne na Unix sistemy?
- Klient
-
- Dlya zapuska na platformah MS Windows vozmozhna kompilyaciya C
- biblioteki libpq, psql, drugih interfesov i klientskih prilozhenij. V

Takzhe suschestvuet versiya sportirovannaya pod Novell Netware 6 na

1.7) Kakaya poslednyaya versiya?
- Poslednij vypusk PostgreSQL - `eto versiya 7.4.2
+ Poslednij vypusk PostgreSQL - `eto versiya 7.4.5
My planiruem vypuskat' novye versii kazhdye 6-8 mesyacev.
3.5) Kak mne upravlyat' soedineniyami s drugih komp'yuterov?
Po umolchaniyu, PostgreSQL razreshaet tol'ko soedineniya na lokal'noj
- mashine cherez sokety domena Unix. Drugie mashiny ne smogut
- podklyuchit'sya k baze poka ne budet vklyuchena opciya tcpip_sockets v

+ host-avtorizaciya v fajle $PGDATA/pg_hba.conf.
3.6) Kakie nastrojki mne nuzhno sdelat' dlya uluchsheniya
proizvoditel'nosti?
provedeniya obnovleniya mozhet byt' ispol'zovan scenarij pg_upgrade
bez ispol'zovaniya dump/restore. Kommentarii k vypusku govorit kogda
mozhno ispol'zovat' pg_upgrade dlya `etogo vypuska.
+
+ 3.11) Kakoe komp'yuternoe "zhelezo" ya dolzhen ispol'zovat'?
+
+ Poskol'ku "zhelezo" personal'nyh komp'yuterov yavlyaetsya naibolee
+ sovmestimym, lyudi sklonny verit', chto takoe "zhelezo" imeet
+ odinakovoe kachestvo. `Eto ne tak. Pamyat' ECC, SCSI i kachestvennye
+ materinskie platy yavlyayutsya bolee nadiozhnymi i imeyut bolee
+ luchshuyu proizvoditel'nost', chem menee dorogoe "zhelezo". PostgreSQL
+ budet rabotat' na lyubom "zheleze", no esli dlya vas vazhny
+ nadiozhnost' i proizvoditel'nost', to s vashej storony budet mudro
