Hi Team

--snapshot=snapshotname
(Use the specified synchronized snapshot when making a dump of the database

This option is useful when needing to synchronize the dump with a logical replication slot) as per the pgdg

How do we synchronize the dump with a logical replication slot with --snapshot?

I am using the postgresql 14 version which supports only pg_create_logical_replication_slot. How to generate a internal snapshot with it ?

Below CREATE_REPLICAION_SLOT not supported by postgresql 14

example osdb_lsr=# CREATE_REPLICATION_SLOT lsr_sync_01 LOGICAL pgoutput;
  slot_name | consistent_point | snapshot_name | output_plugin
-------------+------------------+---------------------+---------------
 lsr_sync_01 | 0/C000110 | 00000003-00000002-1 | pgoutput

Regards,

Durga Mahesh
