This commit is creating a compilation warning on Windows:
multirangetypes.c(1033): warning C4715: 'multirange_constructor0' :
not all control paths return a value

See for example woodlouse:
https://buildfarm.postgresql.org/cgi-bin/show_stage_log.pl?nm=woodlouse&dt=2020-12-21%2001%3A42%3A28&stg=make

Looking at the code, it is obvious that the compiler cannot understand
that this should always return.  Please find attached a suggestion of
patch.

Thanks,

Michael
