# This playbook will generate on-the-fly migration plan for
# PostgreSQL Clusters using logical replication with 0 downtime:
#
# 1. Define migration task (e.g. files/migration/pg-meta.yml)
# 2. Generate migration manual & scripts with:
# ./pgsql-migration.yml -e@files/migration/pg-meta.yml
# 3. Following the manual and execute scripts one by one
#
