go/adbc/driver/snowflake: GetObjects panics while retrieving table columns of vector type #2544
Description
What happened?
When a table contains a column of VECTOR data type, the driver panics:
panic: runtime error: invalid memory address or nil pointer dereference
To my understanding, this is not a supported type by this driver or Go clients in general.
However, the driver could return a clearer error message.
Stack Trace

How can we reproduce the bug?
- Create the table described in this doc: https://docs.snowflake.com/en/sql-reference/data-types-vector#loading-and-unloading-vector-data
- Send a
