Problemi di aggiornamento di Postgres con pg_upgrade

Question

Sto provando ad aggiornare 9.5.5 a 12.3 usando pg_uprade, ho ricevuto il seguente errore

Le dimensioni dei segmenti di relazione massima pg_controldata vecchia e nuova non sono valide o non corrispondono

9.5.5

Blocchi per segmento di grande relazione: 8388608

12.3

Blocchi per segmento di grande relazione: 131072

8388608 blocchi è equivalente a 64 GB.

Ho ricompilato la versione 12.3 utilizzando le seguenti opzioni

./configure --prefix = / opt / pgsql / PostgreSQL-12 --with-segsize = 64

Uscita pg_controldata 9.5.5

E ho eseguito di nuovo pg_upgrade e ottieni lo stesso errore di cui sopra. Cosa mi manca qui?

Answer 1

Sembra che tu abbia pubblicato pg_controldatadue volte l' output per PostgreSQL 9.5.

Ad ogni modo, dovrai configurare PostgreSQL v12 con una dimensione del segmento di tabella non standard:

./configure --prefix=/opt/pgsql/PostgreSQL-12 --with-segsize=64

Inoltre, durante initdb, dovrai specificare la dimensione del segmento WAL non standard:

initdb ... --wal-segsize=64 /path/to/datadir

Quindi pg_upgradedovrebbe avere successo (se le impostazioni locali ecc. Corrispondono).

Answer 2

Quindi, dopo numerosi test, ho trovato il problema. Se eseguo configure --with-segsize = 64 su RHEL 6.10, la dimensione del segmento non verrà impostata su 64 GB, ma se lo eseguo su RHEL 7.8, lo fa. Sembra un bug con RHEL 6.10.
