pg_replslot_reader

==================

Utility to display information about replication slots stored in

the PostgreSQL data directory, regardless of whether the server

is running or not.

It is designed to be independent of PostgreSQL version, provided the

version is at least 9.4 (when replication slots were introduced).

Replication slot state is kept as on-disk data, not in the system

catalogue, due to the requirement to make them available on standbys

for cascaded standby setups.

This utility serves little practical purpose.

Installation

------------

Simply:

    USE_PGXS=1 make install

which will place the `pg_replslot_reader` binary in the PostgreSQL

directory determined by whatever `pg_config` is found in the path.

Usage

-----

Provide the data directory to examine with `-D/--pgdata`.

Example:

    pg_replslot_reader -D ~/devel/postgres/data/head

    Checking directory /home/barwick/devel/postgres/data/head...

    1 replication slot(s) found

    foo
