I am importing recent changes into my reloption patch and came to a question,
I did not find an answer...
vacuum_index_cleanup option exists for both heap and toast relations.
As I understand from documentation index cleanup is about is about reporting
access method that some tuples in table that were indexed are dead, and should
be cleaned.
And as far as I get, we do not index any TOAST tuples directly. They are
obtained by getting relation tuple, and then deTOAST it.
So I do not understand why do we need vacuum_index_cleanup for TOAST tables.
May be we should remove it from there??
Or if I am wrong, can you explain where it is needed?
