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
commands.  Quoting the first argument to COPY does not convert forward
to backward slashes, but COPY does properly process quoted forward
slashes in the second argument.

Win32 COPY works with quoted forward slashes in the first argument only if the
current directory is the same as the directory of the first argument.

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
when building the binary, or adding -lpthread to the shared library
build.  This patch has the effect of doing the later by adding both
-pthread and -lpthread when building libpq.

of '.' or '..'.  Extend canonicalize_path() to trim off trailing occurrences
of these things, and use it to fix up paths where needed (which I think is
only after places where we trim the last path component, but maybe some
others will turn up).  Fixes Josh's complaint that './initdb' does not
work.

that Windows seems exceedingly unfriendly to slashes in shell commands,
as per recent discussion.
