Package "postgresql-12-slony1-2"

replication system for PostgreSQL: PostgreSQL 12 server plug-in
Slony-I is an asynchronous master-to-multiple-slaves replication system
for PostgreSQL with cascading and slave promotion.

This package contains the support functions that are loaded into the
PostgreSQL database server. It needs to be installed on the hosts where
the database server nodes are running. This package works with version
12 of the PostgreSQL server; you need the package that corresponds to
the version of your database server.

The actual replication daemon and the administration tools are in the
package slony1-2-bin. This package is useless without slony1-2-bin installed
somewhere in the network.
