pg_upgrade의 Postgres 업그레이드 문제

Question

pg_uprade를 사용하여 9.5.5를 12.3으로 업그레이드하려고하는데 다음 오류가 발생했습니다.

이전 및 새 pg_controldata 최대 관계 세그먼트 크기가 잘못되었거나 일치하지 않습니다.

9.5.5

큰 관계의 세그먼트 당 블록 : 8388608

12.3

큰 관계의 세그먼트 당 블록 : 131072

8388608 블록은 64GB에 해당합니다.

다음 옵션을 사용하여 12.3 버전을 다시 컴파일했습니다.

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

pg_controldata 출력 9.5.5

그리고 pg_upgrade를 다시 실행하고 위와 같은 오류가 발생합니다. 내가 여기서 무엇을 놓치고 있습니까?

Answer 1

pg_controldataPostgreSQL 9.5 에 대한 출력을 두 번 게시 한 것 같습니다 .

어쨌든 비표준 테이블 세그먼트 크기로 PostgreSQL v12를 구성해야합니다.

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

또한에서는 initdb비표준 WAL 세그먼트 크기를 지정해야합니다.

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

그런 다음 pg_upgrade성공해야합니다 (로케일 등이 일치하는 경우).

Answer 2

그래서 수많은 테스트를 거쳐 문제를 발견했습니다. RHEL 6.10에서 configure --with-segsize = 64를 실행하면 세그먼트 크기가 64GB로 설정되지 않지만 RHEL 7.8에서 실행하면 설정됩니다. RHEL 6.10의 버그처럼 보입니다.
