Can you help me how can I do this?
Here is what I was doing before, which triggered the bug:
pg_restore --schema-only --format=custom --single-transaction $BACKUP_FILE
pg_restore --list $BACKUP_FILE > dump_list.full
grep -v "public events_map" dump_list.full > dump_list.main
pg_restore --data-only --format=custom --use-list=dump_list.main --jobs=4
$BACKUP_FILE
If it's not clear, I'd like to restore the original database 1:1, but
without the data included in the "events_map" table. I mean the results
should be the same as if I'd run truncate after import.
