I did not check how these call behave individually, just a few comments while putting my eyes on the patch. + if (!IsUnderPostmaster) + elog(ERROR, + "slot operation is prohibited in the single user mode"); elog() should not be used for failures that can be user-facing as this would not provide any translation. I'd suggest rewording the error message to provide some more context, as well, say: "cannot use %s in single-user mode", "function_name" -- Michael
