Invalid page header in block xxxx
Hello:
I am a new user of postgresql. I am using postgresql 7.3.4 and I had
inserted about 1.7 million records to a table. When I vacuum / select * from
table, it gets a error message of : Invalid page header in block xxx of
TableA. I check that I still can insert records to the table. But I am not
able to get part of the data (as I try to copy all records to text file,
only around 1.6 million records are copied.)
How can I recovery the data, and how can I prevent the occurrence of this
error? I am only using the default config in postgresql.conf.
Thanks a lot!
Carmen

It sounds to me like you have unreliable disk hardware --- I'd suggest
running badblocks or some other disk-tester program to look for problems.
