Обсуждение: pgsql: Use thread-local storage for querybuffer in fmtId() on Windows,

Log Message:
-----------
Use thread-local storage for querybuffer in fmtId() on Windows, when needed (i.e. when
running pg_restore, which might run in parallel).
Only reopen archive file when we really need to read from it, in parallel code. Otherwise,
close it immediately in a worker, if possible.
