Can't compile against pg13 no such file - utils/jsonapi.h

[robe]

It seems debbie is now unhappy, but her unhappiness I think is unrelated to any changes in PostGIS.

Here pg13 is throwing this during compile

18:41:31 lwgeom_out_geojson.c:20:10: fatal error: utils/jsonapi.h: No such file or directory
18:41:31    20 | #include "utils/jsonapi.h"
18:41:31       |          ^~~~~~~~~~~~~~~~~

Seems to have started happening after her build of pg13
