I have run pg_autovacuum on AIX, so that can, at least loosely, be
considered "tested." And I have turned all of the 7.4 HISTORY material into DocBook for release.sgml Christopher Browne

pg_autovacuum requires that the statistics system be enabled and

shown to have a significant cost under certain workloads. For instance,

a tight loop of queries performing "select 1" was found to run nearly

30% slower when stats were enabled. However, in practice, with more
|

realistic workloads, the stats system overhead is usually nominal.
