Hi all,

Currently pg_dump does not allow a user to specify an exported snapshot
name that he would like to use for a dump using SET TRANSACTION SNAPSHOT
(now pg_export_snapshot is only used for parallel pg_dump within it). I
imagine that this would be handy to take a consistent dump of a given
database after creating a logical replication slot on it. Thoughts?
Regards,
