> I was reading about what the recommendation is around Multi-column indexes
vs single -- and looks like it isn't as simple as I had initially thought that
the multi-column index with a leading column can remove the need of a separate
"single-col" index in all cases!
I did not really see anything in there that suggested that it's not true.
If you have index on x, y, the queries on x are covered by the index.
That's true. Now, sure, an index on x alone be smaller.
Yes. But it remains to be shown what difference that makes.
