This is a good thing in any case, particularly so on Windows which
cannot drop the table file otherwise.

accept the syntax without.  Minor editorialization in the reference pages
for these commands, too.

and doesn't process forward slashes in the same way as external

test only tests for building a binary, not building a shared library.

On Linux, you can build a binary with -pthread, but you can't build a
binary that uses a threaded shared library unless you also use -pthread

-pthread and -lpthread when building libpq.
