yes, there are no too much possibilities, how to do it. Effective implementation needs a special PLpgSQL statement - but I am 100% happy with proposed syntax. We introduce a new special keyword just for one simple construct. A some languages has a generic PRAGMA keyword. So I would be much more happy with something like PRAGMA Assert(found); It is much more close to ADA, and it allows a reuse of new keyword for any other usage in future (your proposal is too simply, without possibility open new doors in future). And we can define a some standard predefined asserts too - like Assert, AssertNotNull, AssertNotEmpty, ... other issue - A asserts macros has one or two parameters usually. You should to support two params assert (with message). > > Regards, > Marko Tiikkaja >
