Is there a way to translate pg_amop.amopstrategy into a description?

I'm digging into GiST indexes again, and ran into a helpful script here:

https://medium.com/postgres-professional/indexes-in-postgresql-5-gist-86e19781b5db

(This piece has shown up in many places in various versions.) I've adapted
the search a little, as I'd like to make it easier to explore available
index ops:

SELECT amop.amopopr::regoperator AS operator,
iif(amop.amoppurpose = 's', 'search','order') AS purpose,
amop.amopstrategy AS
stratgey_number -- I'd like to translate this into a description

FROM pg_opclass opc,
pg_opfamily opf,
pg_am am,
pg_amop amop

WHERE opc.opcname = 'gist_trgm_ops'
AND am.amname = 'gist'
AND opf.oid = opc.opcfamily
AND am.oid = opf.opfmethod
AND amop.amopfamily = opc.opcfamily
AND amop.amoplefttype = opc.opcintype;

+------------------+---------+-----------------+
| operator         | purpose | stratgey_number |
+------------------+---------+-----------------+
| %(text,text)     | search  | 1               |
| <->(text,text)   | order   | 2               |
| ~~(text,text)    | search  | 3               |
| ~~*(text,text)   | search  | 4               |
| ~(text,text)     | search  | 5               |
| ~*(text,text)    | search  | 6               |
| %>(text,text)    | search  | 7               |
| <->>(text,text)  | order   | 8               |
| %>>(text,text)   | search  | 9               |
| <->>>(text,text) | order   | 10              |
| =(text,text)     | search  | 11              |

What I'm hoping for is a function like
get_opt_class_strategy_description(optclass, straregy_number) I've
looked at the source a bit, and it seems that there is no such
function, and that it might well be difficult to implement. The
strategy numbers are, as far as I can see, local to the specific
opt_class, which has no requirement to label them in any particular
way.

Does anyone know if I'm missing something?

Along the way, I did find that you can often look things up by hand in
the source for specific tools, or review a lot of the strategies in
one place:

https://github.com/postgres/postgres/blob/edcb71258504ed22abba8cc7181d2bab3762e757/src/include/catalog/pg_amop.dat#L82

It's easier to use the docs at that point.

No lives hang in the balance here, but I'm hoping to learn something.

Thanks for any help or clarification.
