Support for registering user-defined functions

[IlyaEp]

I noticed that DuckDB Python API allows users to create custom functions:

https://duckdb.org/docs/stable/clients/python/function#creating-functions

import duckdb
con = duckdb.connect()
con.create_function(name, function, parameters, return_type)

Is there currently a way to register user-defined functions via the DuckDB JDBC driver, similar to create_function in the Python API?
If not, is this something that is planned or being considered?

Hi, thanks for the report! No, there is currently no support for UDFs in JDBC driver. It is planned, but there is currently no ETA. See also #256 and #109.
