pg_restore cannot read archives newer than itself, so importing a dump
made by pg_dump from PostgreSQL 17+ into a panel with an older
postgresql-client failed with a raw 'unsupported version (1.16) in file
header' - and only after Xray had already been stopped for the restore.
Probe the uploaded file with pg_restore --list first, which reads only
the archive TOC without touching the database, so an unreadable dump is
rejected before Xray is interrupted. When the failure is a dump-format
version mismatch, translate it into a message naming the PostgreSQL
version that produced the dump and the client version to install.
