Yeah. Looking at
https://coverage.postgresql.org/src/test/regress/regress.c.gcov.html
it's evident that none of these functions are actually exercised
in the regression tests:

regress_dist_ptpath unreferenced anywhere
regress_path_dist unreferenced anywhere
poly2path unreferenced anywhere
widget_in used in type definition, but no input ever happens
widget_out used in type definition, but no output ever happens
pt_in_widget used for operator that evidently isn't called
boxarea SQL function is created, but used nowhere
funny_dup17 SQL function is created, but used nowhere
int44in used in type definition, but no input ever happens
int44out used in type definition, but no output ever happens
test_fdw_handler used by dummy FDW tests

I'm inclined to just remove regress_dist_ptpath, regress_path_dist,
poly2path, boxarea, and funny_dup17. The others might better be dealt
with by making some actual use of them, since those type and operator
creation commands seem to have some test value of their own.

I notice BTW that int44in and int44out are not inverses, ie int44out
produces a string that int44in can't read :-(. We'd definitely have to
fix that if we wanted to make any real use of the type.
