Unless there are any objections, I'll commit the patch with
the following commit message:
------------------
pg_dump: Fix incorrect archive format shown in error message.
In pg_dump and pg_restore, _allocAH() calls _discoverArchiveFormat() to
determine the archive format when the input format is unknown one.
If the input or discovered format is unrecognized, it reports an error
including the archive format number.
If discovered format is unrecognized, its number should be shown in
the error message. But previously the error message mistakenly showed
the originally requested format number (i.e., unknown one) instead of
the discovered one, due to referencing the wrong variable in the error
message.
This commit corrects the issue by using the appropriate variable in
the error message.
In practice, this has no visible effect for users, since
_discoverArchiveFormat() does not currently return unrecognized formats,
so the error condition is never actually triggered.
Back-patch to all supported versions.
