hi experts recently we need to enable "replace" function for our customer, like replacing all the X with Y in "123X456X". According to https://calcite.apache.org/docs/reference.html the replace function seems not implemented. I see there's another function called "OVERLAY", however it's replacing with "index" instead of a "pattern".
Is there any plans to support replace function? Do I have to implement a UDF by myself now? -- Regards, *Bin Mahone | 马洪宾*
