Search the -general mailing list archives for "reattach to shared
memory". The issue has been around for a while but until recently nobody
could reproduce it well enough to isolate it and test possible fixed.
You'll see some recent discussion and a proposed patch.
Try upgrading to the latest version in the 8.3 series. If you still see
the problem please follow up here, or try the patch for the issuye
proposed on the pgsql-general list.
