I think we should put a centralized level check

ones.
Yeah, that seems ok to change. The previous coding style is more useful
if you have a lot of debug messages in a hot code path, but that usually
doesn't apply to where this is used.
The patch I presented keeps the unlikely() checks in the debug-level
macros. Do you think we should drop those too? I figured that avoiding
evaluating the arguments would be worth something.
Oh, that's right, the whole thing is to not evaluate the arguments if
the log level isn't adequate. We should probably keep that.
Is the code size a big problem? ereport() has a bunch of extra code
around each call as well. Does it have similar problems?
