Hi all, I could find several distinct values for column “source” in pg_settings view. Examples of these values are: client, environment variable, configuration file, default, database, override, session. Are there other values? The documentation doesn’t mention any thing (Any way I didn’t find). In some of my databases, I have this: postgres# select name, source from pg_settings where source like 'environ%'; name | source -----------------+---------------------- max_stack_depth | environment variable What is the meaning of ‘environment_variable’ here? For the other listed values, I have “almost” got it but I don’t see anything for “environment variable”. Thanks in advance Michel SALAIS |
