<productname>PostgreSQL</productname> recovers automatically after crash
using the write-ahead log (see <xref linkend="wal">) and no manual
operations are normally needed. However, if there was a transaction running
when the crash occured that created or dropped a relation, the
transaction might have left a stale file in the data directory. If this
happens, you will get a notice in the log file stating which files can be
deleted.
