Comment (by pramsey):

 So, we have had typmod support for literally decades, but I guess the Esri
 code has never been updated, so it's still using the AddGeometryColumn
 shim. To make this right we are going to first have to revert #5829 and
 replace it with the discussed regexp fix instead. Then we are going to
 have to update AddGeometryColumn and associated friends to *not* create
 constraints anymore (why didn't we do this originally???) but to just use
 normal `CREATE TABLE` syntax with typmods.
