7.4.6 docs, chapter 21.2 Routine Reindexing
has a very limited amount of information.
it would be good to know how much of this is taken care of VACUUM and under what circumstances it is needed to do reindex.
it would also be good to add some information on how to disable/enable autoamtic reindex on insert/update/delete if such automatic reindexing exists.
if it is available somewhere else, please write a note on where to find more info.
in chapeter 21.1 i could as well be an idea writing a line or two about what (if any) vacuum does to indecies.
