Not wrong.  Using small-case characters separated with underscores
would be more consistent with the rest perhaps?  We use that for the
initialization of custom variables and for all the relkind-related
interfaces.

Hmm.  I didn't expect it to be this confusing with relopt_type_size[].
I'll try to think about something :(

+ *     Parses reloptions provided by the caller in text array format and
+ *     fills and returns a struct containing the parsed option values
The sentence structure is weird, perhaps:
This routine parses "reloptions" provided by the caller in text-array
format.  The parsing is done with a table describing the allowed
options, defined by "relopt_elems" of length "num_relopt_elems".  The
returned result is a structure containing all the parsed option
values.

Okay, let's check if Nikolay likes this idea.
