Issue with PSQL JDBC Driver Null Pointer

Hello,

I am getting an NPE exception in the JDBC driver 42.2.23.

When the alias is null, NPE results. Is it possible to handle null value ?
I have filled a bug against RCA
https://github.com/vladmihalcea/hibernate-types/issues/335. But, I thought
that PSQL Driver can handle it more gracefully.

Caused by: java.lang.NullPointerException: null
