Bucardo itself is a Perl daemon that communicates with a Bucardo configuration database and the databases that are being replicated. The server that it runs on must have:
bucardo help <subcommand>
Bucardo requires a database to install the main bucardo schema on. This database must be Postgres version 8.1 or higher, and must have both the languages PL/pgSQL and PL/PerlU available. In addition, the install script requires installation as a superuser: creating a new user named ‘bucardo’ for this purpose is highly recommended.
Databases involved in replication must be Postgres version 8.1 or higher. The language PL/pgSQL must be available as well, unless the database is only used as a target for “fullcopy” syncs, in which case 8.1 is the only requirement.
In addition, the Bucardo daemon requires a Unix-like system. It has primarily been tested on Linux variants and macOS, but it should work on FreeBSD, OpenBSD, NetBSD, Solaris, and other similar systems. Bucardo will not currently work on Windows. However, you can have a Bucardo daemon on a Linux server that replicates between two Windows PostgreSQL servers.
