This works because there is a "." in the name. Without the "." PostgreSQL complains: hjp=> set rls_tenant_id=42; ERROR: unrecognized configuration parameter "rls_tenant_id" I think I sort of knew this but had forgotten about it, so checked the manual for the exact rules. Unfortunately I couldn't find them (I checked https://www.postgresql.org/docs/14/sql-set.html, https://www.postgresql.org/docs/14/config-setting.html, https://www.postgresql.org/docs/14/functions-admin.html#FUNCTIONS-ADMIN-SET, and browser the table of content and the index). From the documentation I get the impression that you can only set existing parameters, not your own. I therefore suggest adding something like this to the section "configuration_parameter" in https://www.postgresql.org/docs/14/sql-set.html: | In addition, any name including a single dot (".") can be set.

(This of course assumes that the behaviour is intentional and not a bug.) hp -- _ | Peter J.
