In the attached patch example I have defined a new macro StaticAssertDecl. A typical usage of it is shown in the relpath.c file. The goal was to leave all existing Postgres static assert macros unchanged, but to allow static asserts to be added in the code at file scope without the need for the explicit ct_asserts function. Notice, in reality the StaticAssertDecl macro still uses a static function as a wrapper for the StaticAssertStmt, but now the function is not visible in the source. If this strategy is acceptable I will update my original patch to remove all those ct_asserts functions, and instead put each StaticAssertDecl nearby the array that it is asserting (e.g. just like relpath.c) Kind Regards, Peter Smith --- Fujitsu Australia
