What does Index scan (all rows) mean?

Index Scan Scan MYTable using index FK_1 (all rows)

Will this mean, that SQLA uses the foreign key but will still read all rows of the table?

Is that an IndexOnly scan (i.e. one that would not need to read additional table pages)?

no, it will have to read also non indexed columns, anyway the restriction through the index would already restrict the rows which have to be visited at all.
