Timeline history files can be needed multiple times, ok. My question
was about WAL files only.
I'm tempted to use a restore_command which does cp for history files
and mv for WAL files, to optimize performance and disk usage.
An AI told me that a second restore attempt for the same WAL file
could only happen if recovery is resumed after a crash.

Kind regards
