This utility allows you to run multiple queries simultaneously and view their results. SQLPro for Postgres also supports the creation of custom queries, with auto-completion and syntax highlighting for an improved experience. Meanwhile, SQLPro for Postgres enables you to drop or rename tables and even change rows and columns through an intuitive graphical user interface. To simplify your activities, you also have the option to import data from a CSV file. In the SQLPro for Postgres main window, you can view the structure of the database and create new queries or tables. Manage your Postgres database, run queries and analyze results in real time The best part is that you can save the configuration, which means next time you can connect to the same Postgres database with just a click of the mouse. Note that through the Advanced menu you can change the connection time zone, create an SSL configuration or activate an SSH tunnel. To upgrade an existing installation from md5 to scram-sha-256, after having ensured that all client libraries in use are new enough to support SCRAM, set password_encryption = 'scram-sha-256' in nf, make all users set new passwords, and change the authentication method specifications in pg_hba.conf to scram-sha-256.Additionally, you can change the default server port and specify the database to use. This is no longer possible.) To check the currently stored password hashes, see the system catalog pg_authid. (Previous PostgreSQL releases supported storing the password on the server in plain text. If a password was encrypted using the md5 setting, then it can be used only for the md5 and password authentication method specifications (again, with the password transmitted in plain text in the latter case). The authentication method specification md5 will automatically switch to using the scram-sha-256 method in this case, as explained above, so it will also work. ![]() If a password was encrypted using the scram-sha-256 setting, then it can be used for the authentication methods scram-sha-256 and password (but password transmission will be in plain text in the latter case). This is controlled by the configuration parameter password_encryption at the time the password is set. The availability of the different password-based authentication methods depends on how a user's password on the server is encrypted (or hashed, more accurately). SQLPro makes creation, entry and retrieval from a Postgresql database located on a remote server nearly as easy to carry out as it is with a local SQLite database. If no password has been set up for a user, the stored password is null and password authentication will always fail for that user. Postgresql is an open source (free) database system that is very similar in syntax to SQLite, and which accommodates multiple simultaneous calls for data. Passwords can be managed with the SQL commands CREATE ROLE and ALTER ROLE, e.g., CREATE ROLE foo WITH LOGIN PASSWORD 'secret', or the psql command \password. The password for each database user is stored in the pg_authid system catalog. PostgreSQL database passwords are separate from operating system user passwords. (Though SSL certificate authentication might be a better choice if one is depending on using SSL). If the connection is protected by SSL encryption then password can be used safely, though. The method password sends the password in clear-text and is therefore vulnerable to password “ sniffing” attacks. To ease transition from the md5 method to the newer SCRAM method, if md5 is specified as a method in pg_hba.conf but the user's password on the server is encrypted for SCRAM (see below), then SCRAM-based authentication will automatically be chosen instead. The md5 method cannot be used with the db_user_namespace feature. Also, the MD5 hash algorithm is nowadays no longer considered secure against determined attacks. It prevents password sniffing and avoids storing passwords on the server in plain text but provides no protection if an attacker manages to steal the password hash from the server. The method md5 uses a custom less secure challenge-response mechanism. This is the most secure of the currently provided methods, but it is not supported by older client libraries. It is a challenge-response scheme that prevents password sniffing on untrusted connections and supports storing passwords on the server in a cryptographically hashed form that is thought to be secure. The method scram-sha-256 performs SCRAM-SHA-256 authentication, as described in RFC 7677. ![]()
