Is there a link between Sybase and Postgres? I ask because I came across a bug in Netezza, and Netezza has a well-known Postgres lineage, but when web-searching the bug, the first thing I found was a Sybase reference- http://geekswithblogs.net/marocanu2001/archive/2011/08/11/nasty-bug-in-sybase-iq-analytical-function-last_value-over-partition.aspx and indeed that is the exact bug I found in Netezza! "first_value" works great, "last_value" has window size 1 unless you also say "rows between unbounded preceding and unbounded following". Two unrelated commercial products with the same bug makes me wonder... does/did Postgres also have this issue, with both NZ and Sybase importing the same buggy code? -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
