As usual, following item in the 8.1.5 release note is pretty vague: * Efficiency improvements in hash tables and bitmap index scans(Tom)

Any idea? -- Tatsuo Ishii SRA OSS, Inc. Japan ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
