I renamed this function to IndexRelationGetParentRelation and muved to
relcache.c

I don't call a quote_identifier on only data error properties like
table_name or schema_name (but I am open to arguments for it or
against it). The quote_identifier is used for column names, because
there should be a more names and comma should be used inside name -
and this is consistent with pg_get_indexdef_columns.
