<para>

Altering the <literal>publish_via_partition_root</literal> parameter can

lead to data loss or duplication at the subscriber because it changes

the identity and schema of the published tables. Note this happens only

when a partition root table is specified as the replication target.

<para>

This problem can be avoided by refraining from modifying partition leaf

tables after the <command>ALTER PUBLICATION ... SET</command> until the

<link linkend="sql-altersubscription"><command>ALTER SUBSCRIPTION ... REFRESH PUBLICATION</command></link>

is executed and by only refreshing using the <literal>copy_data = off</literal>

option.
