Well, I would use the Hadoop FDW:
https://github.com/EnterpriseDB/hdfs_fdw
and it only supports these authentication methods:
Authentication Support
The FDW supports NOSASL and LDAP authentication modes. In order to use
NOSASL do not specify any OPTIONS while creating user mapping. For LDAP
username and password must be specified in OPTIONS while creating user mapping.
Not every FDW supports every Postgres server authentication method.
