Sure, there are a couple of places we can do it:
1) We can add the pragma at the top of the file, which will turn it off
for that file, but keep it for other files.
2) We can turn it off on a per-project basis, meaning we turn it off for
the entire backend and the entire psql, but not for other EXEs and DLLs.
3) We can just turn it off for everything

Note that it'll of course turn off the warning in *all* cases, not just
the "free const chra **"-one.

Which way would be preferred?
