Use "COPY table TO" for partitioned tables in initial table synchronization.
Commit 4bea91f added support for "COPY table TO" with partitioned
tables. This commit enhances initial table synchronization in logical
replication to use "COPY table TO" for partitioned tables if possible,
instead of "COPY (SELECT ...) TO" variant, improving performance.
