#Postgresql for mac buggy upgrade#
The hard parts are that you have to set all the passwords again, and that you may have to upgrade the client software. You can see from the above that it is not so difficult to change from md5 to scram-sha-256. Then check the log file or examine the view pg_hba_file_rules to see if the reload was successful.
#Postgresql for mac buggy password#
That will prevent users who still have an old MD5 password from authenticating.Īfter that, reload the configuration as above. Still, you should adapt pg_hba.conf by replacing all occurrences of “ md5” with “ scram-sha-256”. This step is not strictly necessary, because PostgreSQL will use scram-sha-256 authentication for scram-sha-256-hashed passwords, even if the authentication method is set to md5 in pg_hba.conf. Change the authentication method in pg_hba.conf Before proceeding with the next step, examine the table pg_authid and make sure that it contains no more MD5 hashed passwords. In psql, a superuser can change any user’s password withĮven if the user sets the same password as before, the password will now be hashed with SHA-256. Set all passwords againĪll password authenticated users have to change their password. Note that even though you changed the parameter, the old MD5 passwords still work, as long as the authentication method in pg_hba.conf is set to md5. Look into the log file to see if the reload was successful, and check the new value via SQL: Alternatively, you can run this SQL statement: Where /postgres/datadir is the PostgreSQL data directory. Make sure you remove the hash ( #) at the beginning of the line.

Change the password_encryption parameterĮdit nf and change the parameter to This is a good idea anyway, as it is never smart to get stuck with old, unmaintained software.
#Postgresql for mac buggy drivers#
Upgrade all PostgreSQL client software and drivers that are too old to support the new authentication method.

It is actually not difficult to convert to scram-sha-256, if you follow these guidelines: 1. Step-by-step instructions for switching to scram-sha-256 Old versions of Npgsql will come back with:Īuthentication method not supported (Received: 10) The authentication type 10 is not supported. The error message you get with an old version of libpq when you attempt to connect to a server that requires scram-sha-256 authentication is:
