Behebung eines beschädigten Indexes PG16.3 (Wiederherstellung aus Backup nicht möglich – konnte eindeutigen Index nicht erstellen)

Unterstützung

Ich habe versucht, mein Discourse auf einen neuen Server zu verschieben und bin beim Wiederherstellen des Backups auf ein Problem gestoßen:

[2024-09-12 06:57:25] ERROR:  could not create unique index "unique_post_links"
[2024-09-12 06:57:25] DETAIL:  Key (topic_id, post_id, url)=(2026, 4639, http://www.metronet.com/~mob) is duplicated.
[2024-09-12 06:57:27] EXCEPTION: psql failed: DETAIL:  Key (topic_id, post_id, url)=(2026, 4639, http://www.metronet.com/~mob) is duplicated.

Es gibt viele Themen zur Behebung eines beschädigten Index, aber die meisten sind alt. Gibt es eine definitive Anleitung zum Finden und Beheben des Duplikatproblems mit einer neueren PG-Version wie 16? Mein Backup mit Dateien ist 37 GB und ohne Dateien 5 GB groß.

Ich möchte herausfinden, ob es neben dem oben genannten noch weitere Duplikate gibt, bevor ich einen neuen Umzug/Wiederherstellung versuche, da dies sehr lange dauert, dies zu verschieben.

Es ist schon eine Weile her. Es ist keine andere Anmerkung als vor Jahren.

Was zu tun ist, ist, diesen Index auf dem anderen Server neu zu erstellen (vorausgesetzt, er läuft noch) und die doppelten Werte zu löschen (oder anderweitig zu reparieren), und wenn der Index endlich neu erstellt ist, ein weiteres Backup zu erstellen und es auf dem neuen Server wiederherzustellen.

Aber Sie könnten versuchen, das Ganze (aber zumindest die Uploads) mit rsync zu verschieben.

Ich habe die Duplikate entfernt, aber diese zusätzlichen Indizes übrig, die ich meiner Meinung nach löschen sollte. Kann ich alle hier aufgeführten löschen?
