postgresql-13-pglogical - 2.3.3-3+deb11u1 main

The pglogical extension provides logical streaming replication between
PostgreSQL instances, using a publish/subscribe model. Contrary to the
built-in streaming replication, pglogical can replicate between major versions
or different architectures and is not restricted to replicate the entire
instance but can selectively replicate arbitrary sets of tables.
.
Use-Cases include migrations and major-version upgrades, aggregation of
several databases into a Data Warehouse, It utilises the Logical Decoding
features available since PostgreSQL 9.4 working with low overhead on both
provider and subscriber.
