timescaledb backup, pg_dump warnings - Mailing list pgsql-admin

Dear Colleagues,

Is anyone using the Timescaledb extension? I've read
https://docs.timescale.com/latest/using-timescaledb/backup, it says that
restoring data from a backup currently requires some additional
procedures. I'm fine with that.

However, the actual pg_dump produces multiple warnings, do they mean that the
timescaledb database is corrupt, or the dump will come out corrupt?
Below is a sample of the warnings (Postgres 12.6, Timescaledb 2.2.0):

$ pg_dump -Fc -U postgres -f zabbix.dump -d zabbix
pg_dump: warning: there are circular foreign-key constraints on this table:
pg_dump:   hypertable
pg_dump: You might not be able to restore the dump without using --disable-triggers or temporarily dropping the
constraints.
pg_dump: Consider using a full dump instead of a --data-only dump to avoid this problem.
pg_dump: warning: there are circular foreign-key constraints on this table:

pg_dump: You might not be able to restore the dump without using --disable-triggers or temporarily dropping the
constraints.
