I have a table that reports one block error when I try to select
everything, reindex, vacuum, etc. (invalid page header in block
413620 of relation "tablename") I've read on the list that the thing
to do is use pg_dump and then restore it. However, pg_dump fails
with the same error.
I can't take down the whole server, let alone easily Postgresql, to
debug this. Any ideas as to how I could do this? I wrote a Perl
script to select the records one by one but it didn't find a bad
record although maybe it's how I wrote the script (it just selected
the records one by one.)
I also don't know enough about Postgresql data/blocks to figure out
which data is in that block and what I'd do with that.
Thanks in advance. P.S. "relation" means the table, not an index,
right? I don't see an index with the same name as the table, but
thought I'd check.
