And here's another case: SELECT x FROM generate_series(2147483643, 2147483644,5) AS a(x); A step of 1 would work fine, but forcing it to exceed the boundary in this way means it never returns. -- Thom Brown Twitter: @darkixion IRC (freenode): dark_ixion Registered Linux user: #516935 -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
