Hello, I?ve been working with PostgreSQL on Windows for almost a year. But when I put it in production to the customer it has had the following error after a power cut: ?invalid page header in block aaa of relation ?bbb?. ? in which aaa is a block number and bbb is a table. Trying to find out what the problem could be, I could only realized that it breaks the file corresponding to the table leaving it in a format that cannot be read again. I wasn?t able to reproduce the error in any PC of the company. At the beginning I thought it could be a problem from the Cygwin, but I tried the native version for Windows and the mistake goes on. I would like to know if it is something related to PostgreSQL configuration or a mistake. I?m working with Windows 2000 or Windows XP (and both get the same problem). I go to the database through ADO, and I use Delphi as programming language. The PostgreSQL version is version 8 beta 2 for Windows. Besides, none of the database where the error appears is over 300MB. Thanks, and I look forward to receiving your answer as soon as possible.
