PostgreSQL supports a variety of ways of defining parameter settings for various user groups. This is very convenient, especially for managing user groups that have different requirements.
Follow these steps to set parameters at various levels as per the requirements:
- For all users in the
saasdatabase, use the following commands:
ALTER DATABASE saas
SET configuration_parameter = value1;- For a user named
simonconnected to any database, use the following commands:
ALTER ROLE simon
SET configuration_parameter = value2;- Alternatively, you can set a parameter for a user only when they're 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 non-default values.
