Then I'd say it's that apps problem. And it's clearly nothing new - the
problem has existed before. We'd certainly want to document it, though.
I don't think it's a good idea in general to redefine something as
fundamental as select, send, recv etc from libpq-fe.h (or files included
from there). That will affect any and all socket calls in the program in
question, including those that aren't in use in libpq. If we want to
affect those, we need to find a way to do it without exposing it to the
client apps.
