Start BackUp DataBase....

NOTICE: Message from PostgreSQL backend:

The Postmaster has informed me that some other backend died abnormally and

possibly corrupted shared memory.

I have rolled back the current transaction and am going to terminate your d

atabase system connection and exit.

Please reconnect to the database system and repeat your query.

dumpClasses(): command failed. Explanation from backend: 'pqReadData() // backe

nd closed the channel unexpectedly.

This probably means the backend terminated abnormally

before or while processing the request.

backup이라는 script는 제가 만들어 cron으로 해둔 것입니다. 내용은 다음과 같습니다.

pg_dump /d DB /t ad > $WORK/gametek_ad.backup

pg_dump /d DB /t ad_hist > $WORK/gametek_ad_hist.backup

pg_dump /d DB /t addr > $WORK/gametek_addr.backup

pg_dump /d DB /t advertiser > $WORK/gametek_advertiser.backup

pg_dump /d DB /t best_worst > $WORK/gametek_bestworst.backup

pg_dump /d DB /t collect_apply_member > $WORK/gametek_collect_apply_member.

backup

pg_dump /d DB /t collect_member > $WORK/gametek_collect_member.backu

.....

이것을 실행하다가 중간에 에러가 난 것 같습니다.
