Subject: pgsql: Fix lstat() for broken junction points on Windows.

Message-ID: <E1t9Bms-000hQm-SC@gemulon.postgresql.org> (raw)
Fix lstat() for broken junction points on Windows.
When using junction points to emulate symlinks on Windows, one edge case
was not handled correctly by commit c5cb8f3b: if a junction point is
broken (pointing to a non-existent path), we'd report ENOENT. This
doesn't break any known use case, but was noticed while developing a
test suite for these functions and is fixed here for completeness.
Also add translation ERROR_CANT_RESOLVE_FILENAME -> ENOENT, as that is
one of the errors Windows can report for some kinds of broken paths.
