Re: Serious Crash last Friday

ok, I now found out that the table altseiten with the oid 16584
has got the reltoastrelid 16586. this is the oid of pg_toast_16584 which
has the reltoastidxid 16588. this again is the oid of pg_toast_16584_idx.

now doing pg_filedump -i 16588 gives 1213 lines, and in Item 109 there is a
block id: 1048595

Then Item 278 has got Block Id 43, Item 279 Block Id 1, Item 280 Block Id 1,
Item 281 Block Id 52 ... looks strange, too, doesn't it?

what does this mean?
