Hi,
For my project, I need to create a variable argument function which accepts
multiple strings & returns some transformed string. I've gone through the
https://www.postgresql.org/docs/9.6/static/xfunc-c.html doc..But there's no
clear documentation for variable args.
I'able to understand we can have ArrayType as data type for same. But how to
iterate & process it??? Kindly help.
