Обсуждение: 8.1.5 release note
As usual, following item in the 8.1.5 release note is pretty vague: * Efficiency improvements in hash tables and bitmap index scans(Tom) Especially I'm wondering what was actually improved in bitmap index scans. I see several commit messages regarding bitmap index scans, but I cannot figure out which one is related to the item. Any idea? -- Tatsuo Ishii SRA OSS, Inc. Japan

The commit messages are the only way. -- Bruce Momjian bruce@momjian.us EnterpriseDB http://www.enterprisedb.com + If your life is a hard drive, Christ can be your backup. +
