If I set a custom GUC variable to a boolean value, such as:
SET myapp.audit = 'on';
is there a way to test it for truthiness in the same way the standard built-in variables are? IOW, the docs say a boolean can be written as:
Boolean values can be written as on, off, true, false, yes, no, 1, 0 (all case-insensitive) or any unambiguous prefix of these.
Sorry, hit send too soon. I meant to ask, is there a built-in function I can call, given the value from current_setting('myapp.audit'), that will test it using the same logic?
