Hi, I am running postgres 10.3 server on armv71 linux which i've built from source. The server host is a raspberry pi with postgres server running inside a docker container. All filestore is over iscsi. I use postgres to store data for mediawiki. This is a very low throughput environment. I've had no problems with this configuration over recent years and upgraded to postgresql to 10.3 about a year ago with no problems since. About a week ago i found i could not take a backup using pg_dump and the failure message was: chunk 1 for toast value 80945156 in pg_toast_80849380 invalid page in block 1500 of relation pg_tblspc/16387/PG_10_201707211/16392/80912520. I have a filesystem backup of the failing instance. I've tried a reindex which fails with the same error I've tried using zero_damaged_pages which allows the reindex to succeed but then reports the same error still when i attempt to select from the table. What can i do to minimise my data-loss and fixup my instance (if anything)? I have a db backup but its a month old and i'd like to try and recover what data i can from that month.
