Cosmetic gripes: I think we could get rid of the various comments that
say things like "variable length fields start here", since the #ifdef
CATALOG_VARLEN lines now represent that in a standardized fashion.
Possibly those lines should be

#ifdef CATALOG_VARLEN /* variable-length fields start here */

to be even clearer.

What would be appropriate to add instead of those inconsistently-used
comments is explicit comments about the exception cases such as
proargtypes, to make it clear that the placement of the #ifdef
CATALOG_VARLEN is intentional and not a bug in those cases.

regards, tom lane
