Clarify some errors in pg_receivewal when closing WAL segments
A WAL segment closed during a WAL stream for pg_receivewal would
generate incorrect error messages depending on the context, as the file
name used when referring to a WAL segment ignored partial files or the
compression method used. In such cases, the error message generated
(failure on close, seek or rename) would not match a physical file
name. The same code paths are used by pg_basebackup, but it uses no
partial suffix so it is not impacted.
7fbe0c8 has introduced in walmethods.c a callback to get the exact
physical file name used for a given context, this commit makes use of it
to improve those error messages. This could be extended to more code
paths of pg_basebackup/ in the future, if necessary.
Extracted from a larger patch by the same author.
