One more bit of information. The master table has exactly 3 rows missing. They were all inserted half a year ago within one minute and no other rows have been inserted in between them. Is it possible that we lost a consistent piece of data (like a block or a page)? What can I do to track it down? I suspect it is a bug in PostgreSQL. Does it resemble an already submitted issue? -- Konrad Garus -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
