Question

linux

Set up standard replication between two postgresql 10.5.
There are some DB, everyone lies in separate tablespace/lvm.
One of the databases on the master has a size of 100GB on the slave 16GB.
The servers are connected, there are no errors in the log [related to the database.
the backlog in replication does not grow, all other databases are fully replicated

Answer 1

Do the \l+ and \dt+ conclusions in the problem base match on the master and replica?
With streaming replication, the replica is an exact binary copy of the master.
hypotheses:
the database is damaged, but there is no activity in it, and therefore
extra files on the master remain unnoticed
