Get/set_defopt – default connection options Get_pqlib_version – get the version of libpq For details about the installation and deployment operations, see.You have installed the third-party function library PyGreSQL.For details, see Obtaining the Cluster Connection Address. You have obtained the public network address, including the IP address and port number in the data warehouse cluster.The new password will be encrypted using the hash algorithm and stored for authentication in the next connection. For connectivity purposes, you must manually change your password or create a new user. If you change your cryptographic algorithm policy, the database cannot generate a new hash digest for your existing password. During password verification, the system compares the hash digest with the password digest sent from the client (salt operations are involved).

The database stores the hash digest of passwords instead of password text.To use the MD5 algorithm used in an open-source protocol, you must modify your password policy and create a new user, or change the password of an existing user. As a result, the open-source drives and clients may fail to connect to the database.

For security purposes, GaussDB(DWS) no longer uses MD5 to store password digests by default.
