Thread: Cannot pg_dump_all anymore...

I got this error:

pg_dump: error: query returned 0 rows instead of one: EXECUTE 
dumpBaseType('794978')

any clue to solve it?

thanks

David

First figure out which database is having that issue, by using pg_dump --schema-only on each database in turn. Then run this SQL on the database giving the error to see if the type exists, or what is nearby:

select oid, typname, typtype, typnamespace::regnamespace from pg_type where oid <= 794978 order by 1 desc limit 3;

Also let us know the version of pg_dump and the version of Postgres being dumped.

Cheers,

Greg

select oid, typname, typtype, typnamespace::regnamespace from pg_type where oid <= 794978 order by 1 desc limit 3;
  oid   |  typname   | typtype | typnamespace
--------+------------+---------+--------------
 794970 | log_17167  | c       | repack
 794969 | _log_17167 | b       | repack
 794966 | pk_17167   | c       | repack
(3 rows)

Arggh it's repack 🙁

I have no clue how to repair repack....

PG version?

Whole command line, including all error messages?

ok I fixed it with:

SELECT * FROM pg_depend WHERE objid IN (794964, 794968);
DELETE FROM pg_depend WHERE objid IN (794964, 794968);

systemctl restart postgresql

is it possible a crash happened with a VACUUM and a machine reboot in same time?

More likely to be a problem with pg_repack.  Please tell us the exact versions of pg_repack and Postgres in use here.

PG 17.4

pg_repack last git

thanks
