-Before installing **wal2json**, you should have PostgreSQL 9.4+ installed (including the header files). If PostgreSQL is not in your search path, add it. If you are using [PostgreSQL yum repository](https://yum.postgresql.org), install `postgresql13-devel` and add `/usr/pgsql-13/bin` to your search path (yum uses `13, 12, 11, 10, 96 or 95`). If you are using [PostgreSQL apt repository](https://wiki.postgresql.org/wiki/Apt), install `postgresql-server-dev-13` and add `/usr/lib/postgresql/13/bin` to your search path. (apt uses `13, 12, 11, 10, 9.6 or 9.5`).
