Remove the correct pgstat file on DROP DATABASE
We were unlinking the permanent file, not the non-permanent one. Butsince the stat collector already unlinks all permanent files on startup,there was nothing for it to unlink. The non-permanent file remained inplace, and was copied to the permanent directory on shutdown, so ineffect no file was ever dropped.Backpatch to 9.3, where the issue was introduced by commit187492b.Before that, there were no per-database files and thus no file to dropon DROP DATABASE.Per report from Thom Brown.Author: Tomáš Vondra
