PostgreSQL supports a variety of ways of defining parameter settings for various user groups. This is very convenient, especially to manage user groups that have different requirements.
For all users in the saas
database, use the following commands:
ALTER DATABASE saas SET configuration_parameter = value1;
For a user named simon
connected to any database, use this:
ALTER ROLE Simon SET configuration_parameter = value2;
Alternatively, you can set a parameter for a user only when connected to a specific database, as follows:
ALTER ROLE Simon IN DATABASE saas SET configuration_parameter = value3;
The user won't know that these have been executed specifically for them. These are default settings, and in most cases, they can be overridden if the user requires nondefault values.
