Typical markup:
<command>UPDATE</>s and <command>DELETE</>s leave dead tuples
behind, as do failed <command>INSERT</>s. Previously only
<command>VACUUM</> could reclaim space taken by dead tuples. With
- <acronym>HOT</> dead tuple space can be reclaimed at the time of
- <command>INSERT</> or <command>UPDATE</> if no changes are made to
- indexed columns. This allows for more consistent performance.
- Also, <acronym>HOT</> avoids adding duplicate index entries.
