   ### What feature or improvement would you like to see?
   
   [Materialize](https://materialize.com) claims to be wire-compatible with 
PostgreSQL, but I cannot successfully connect to Materialize with the 
PostgreSQL ADBC driver, because in Materialize, `pg_catalog.pg_type` lacks a 
`typsend` column, so [this 
query](https://github.com/apache/arrow-adbc/blob/ef8c485892448350413190639e739679c732cb18/c/driver/postgresql/database.cc#L275-L278)
 fails.
   
   Steps to repro:
   ```sh
   docker run -d -p 127.0.0.1:6874:6874 -p 127.0.0.1:6875:6875 -p 
127.0.0.1:6876:6876 -p 127.0.0.1:6877:6877 materialize/materialized
   ```
   ```py
   from adbc_driver_manager import dbapi
   
   con = dbapi.connect(
       driver="postgresql",
       db_kwargs={
           "uri": "postgresql://materialize@localhost:6875/materialize"
       }
   )
   ```
   This prints the error:
   ```
   Traceback (most recent call last):
     File "/path/to/main.py", line 22, in <module>
       con = dbapi.connect(

           }
       )
