When a password is specified in sql-createrole or sql-alterrole, this parameter determines the algorithm to use to encrypt the password. The default value is
md5, which stores the password as an MD5 hash (
on is also accepted, as alias for
md5). Setting this parameter to
scram-sha-256 will encrypt the password with SCRAM-SHA-256.
Note that older clients might lack support for the SCRAM authentication mechanism, and hence not work with passwords encrypted with SCRAM-SHA-256. See auth-password for more details.
