Back off chattiness in RemovePgTempFiles().
In commit561885d, as part of normalizing RemovePgTempFiles's errorhandling, I removed its behavior of silently ignoring ENOENT failuresduring directory opens. Thomas Munro points out that this is a bad idea atthe top level, because we don't create pgsql_tmp directories until needed.Thus this coding could produce LOG messages in perfectly normal situations,which isn't what I intended. Restore the suppression of ENOENT logging,but only at top level --- it would still be unexpected for a nested tempdirectory to disappear between seeing it in the parent directory andopening it.Discussion:https://postgr.es/m/CAEepm=2y06SehAkTnd5sU_eVqdv5P-=Srt1y5vYNQk6yVDVaPw@mail.gmail.com
