Обсуждение: could not open relation: Invalid argument
Version: PostgreSQL 8.2.5 on i686-pc-mingw32 I recently started getting this error message randomly, "could not open relation 42904/42906/42985: Invalid argument". I also got it for a couple of other files. All three files are related to tables that have just a single row each. I googled the error message and found that this looks like a problem on Windows (which I'm running until we get access to our Linux server) and probably related to anti-virus scanning. Having run Oracle on Windows before, I have experienced the problem with an anti-virus scanner locking a file and causing the database to error. I thought I understood and fixed the problem. Today, I used pgAdmin to Vacuum Analyze the entire database. It flew through this task as my database is fairly small. However, when it got to the three tables that exhibited this error message, it hung. It took maybe 2-3 seconds to vacuum analyze each one of these tables. Now I don't get it. Was there something corrupt in the file and it wasn't related to the anti-virus scanner? Jon

This has been reported before, and we've patched the system so that the error reported is better. In HEAD we also patched it so that the system would automatically retry a number of times if the problem is ERROR_SHARING_VIOLATION (or something like that). That patch was not backported to 8.2 due to lack of testing -- the original reported did not come back to try the patched version. If you want to try, the patch is here: https://projects.commandprompt.com/public/pgsql/changeset/29853 Let us know how it goes. If your problem is easily reproducible and the patch makes it go away, we would consider back-patching the fix.

Sure, I can do that. //Magnus
