I'm using PostgreSQL 9.3.16 on Windows 7 and the data directory was created from a filesystem backup of an installation running on another machine, which failed. After starting the postgres service I ran `pg_dump` using pgAdminIII to backup the databases. pg_dump.exe --host localhost --port 5433 --username "postgres" --no-password --format custom --blobs --verbose --file "db-2017-03-22.backup" "mydb" One of them reported the following error: pg_dump: dumping contents of table "public.bandana" pg_dump: dumping contents of table "public.bodycontent" pg_dump: Dumping the contents of table "bodycontent" failed: PQgetResult() failed. pg_dump: Error message from server: ERROR: missing chunk number 0 for toast value 314936 in pg_toast_36791 pg_dump: The command was: COPY public.bodycontent (bodycontentid, body, contentid, bodytypeid) TO stdout; Process returned exit code 1. Since then I've done some digging around and run the following commands: REINDEX table pg_toast.pg_toast_36791; VACUUM ANALYZE bodycontent; Both return: Query returned successfully with no result in xx ms. Using pgAdmin I've selected the Maintenace option and run a VACUUM (no options) , ANALYSE and REINDEX and no errors were reported. I ran VACUUM with the FULL option and the following error was reported: INFO: vacuuming "public.plugindata" ERROR: missing chunk number 0 for toast value 289849 in pg_toast_36998 I don't have any experience with postgres or databases in general. Can anyone advise what I should do next? -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
