====== Migracija podataka iz PostgreSQL 9.3 u 9.6 bazu ======

Koristeći Pg_dump i psql moguće je preneti podatke iz baze servera verzije 9.3 u bazu servera 9.6.\\
\\
**Obe baze moraju biti iste verzije npr. 10462.10536.20044, a baza na serveru 9.6 mora biti raščlanjena.\\
Pre migracije podataka svi korisnici baze moraju izaći iz programa (Balans, kasa…) jer će se preneti neažurirana tabela UniBroj pa će njene vrednosti biti početne za unibroj sekvence na novom serveru što će dovesti do grešaka tipa "Duplicate key value…"**

1. **Tekuća godina** - npr. PGS server 9.3 na računaru MOC, PGS server 9.6 na računaru 192.168.0.15, baza b7

**Izvoz **podataka komandom
<code>
pg_dump --no-owner --no-privileges --data-only --column-inserts --dbname=postgresql://korisničko_ime:lozinka@MOC:5432/b7 --schema=public --file="F:\b7tekuca.dump"
</code>

Otvoriti fajl nekim editorom teksta npr. Notepad++.\\
Promeniti liniju SET search_path = public, pg_catalog; u SET search_path = btek, bpub, public, pg_catalog;\\
\\
Pre prve INSERT komande dodati:

  * SET session_replication_role = replica; – isključuje strane ključeve
  * Komande za brisanje podataka. Ako baza na serveru 9.6 ima podatke dodati DELETE FROM komande za svaku tabelu, inače samo za tabele koje u nultoj bazi imaju podatke.

Posle poslednje INSERT komande dodati:

  * SET session_replication_role = DEFAULT; – uključuje strane ključeve

Uvoz podataka komandom:

<code>
psql --dbname=postgresql://korisničko_ime:lozinka@192.168.0.15:5432/b7 --file="F:\b7tekuca.dump"
</code>

2. **Prethodna godina**  - npr. PGS server 9.3 na računaru MOC, PGS server 9.6 na računaru 192.168.0.15, baza b7, arhiva 2016

**Izvoz **podataka komandom

<code>
pg_dump --no-owner --no-privileges --data-only --column-inserts --dbname=postgresql://korisničko_ime:lozinka@MOC:5432/b7 --schema=2016 --file="F:\b7_2016.dump"
</code>

Na PostgreSQL serveru 9.6 u bazi b7 odraditi kopiranje scheme tekuće godine u praznu schemu a2016 komandom:

<code>
select _blnscloneschema('btek','a2016',false);
</code>

Dodati komande SET search_path, SET session_replication_role i DELETE FROM "2016".naziv_tabele kao u primeru izvoza tekuće godine.

Uvoz podataka komandom:

<code>
psql --dbname=postgresql://korisničko_ime:lozinka@192.168.0.15:5432/b7 --file="F:\b7_2016.dump"
</code>
