Hi guys.
I know it's not strictly /barman/ list but I presume many
here use it.
I do, but I only now realized that using barman's
/recovery/ with PIT is faulty - apparently have been for a
while.
So I wonder - besides the fault(s) - I must be missing
something or doing something incorrectly for...
when I check backups /wals/ I get:
-> $ pg_waldump
ubusrv-master-10-1-1-88/wals/00000B000000000D/00000B000000000D00000030
pg_waldump: fatal: could not find a valid record after
D/30000000
and that is for every /wal/ in the backup - which has to
wrong, no?
How & where do I start troubleshooting this?
many thanks, L.

The WAL files on the Barman Server might be compressed, depending on your Barman compression setting.
e.g. compression = gzip, or you are using a different PostgreSQL pg_waldump version, than the one on your
PostgreSQL host.
Cheers, William

Hi guys.
I know it's not strictly barman list but I presume many here use it.
I do, but I only now realized that using barman's recovery with PIT is faulty - apparently have been for a while.
So I wonder - besides the fault(s) - I must be missing something or doing something incorrectly for...
when I check backups wals I get:
-> $ pg_waldump ubusrv-master-10-1-1-88/wals/00000B000000000D/00000B000000000D00000030
pg_waldump: fatal: could not find a valid record after D/30000000
and that is for every wal in the backup - which has to wrong, no?
How & where do I start troubleshooting this?
many thanks, L.

across different OSes - which is my env - I should have
thought of this, different versions yes.
thanks, L.

Can *barman* restore the instance? For example, pg_waldump would barf on
WALs in a PgBackRest repo because it's encrypted in addition to being
compressed, even though pgbackrest does PITR restores without complaint.

and yes /restore/ does restore - even though the host is
with different pgsql' libs version, but it does not restore
PITR.
So I wonder now - perhaps PITR not working is not due to the
"well-know" issue, maybe it was but it's not any more, but
it's in my case due to the fact that pgsql server(16) and
barman(13) use different pgsql versions - I'll tamper some
more some day.
thanks, L.
