Update text column, add/remove text at character index

How can I update a text column, adding and/or removing text in the middle of the string?

Examples

Add "abc" to "0123456" at index 3, to make "012abc3456"
Remove index 3 to index 5 of "0123456", to make "0126"

You can use overlay for the first:

select overlay('0123456' placing 'abc' from 4 for 0)

And for the second as well:

select overlay('0123456' placing '' from 4 for 3)
