I see multiple warnings during compilation with 11.0, e.g:

```
pg_thrift.c:1120:72: warning: implicit declaration of function
‘JsonbGetDatum’; did you mean ‘JsonbPGetDatum’?
[-Wimplicit-function-declaration]

pg_thrift.c:1206:13: warning: the address of ‘is_big_endian’ will
always evaluate as ‘true’ [-Waddress]

pg_thrift.c:1227:18: warning: implicit declaration of function
‘PG_GETARG_JSONB’; did you mean ‘PG_GETARG_JSONB_P’?
[-Wimplicit-function-declaration]

pg_thrift.c:1227:18: warning: initialization of ‘Jsonb *’ {aka ‘struct
<anonymous> *’} from ‘int’ makes pointer from integer without a cast
[-Wint-conversion]
```

Also tests (make clean && make && make install && make installcheck)
don't pass.

I believe get field / set field are most common ones. Naturally there
are also enumerations, projections, you name it. You can check out list
of operation supported by JSONB (or a list of operations on dict's in
Python) to get a full picture.
