Compare Postgresql tables

You have servers with master-slave(s) replication and want to be sure what all tables is synced. Program queries count of records for every table in database and shows to you on screen. Used on servers with logical replication and wal-g.

Create config.yaml with connection strings and run compare-pg -config config.yaml. If you want check only single table add argument -table table_name.

Sample config file:

credentials:
  master: postgres://username:password@pg-master.server.ru:5433/mydatabase?sslmode=disable
  slave_logical: postgres://username:password@pg-slave1.server.ru:5432/mydatabase?sslmode=disable
  slave_walg: postgres://username:password@pg-slave2.server.ru:5435/mydatabase?sslmode=disable

Sample output, table user_info is out of sync on slave_logic:
