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
