PostgreSQL zero-downtime migrations made easy
16b1d75ee0
This change adds a new `sql` operation, that allows to define an `up` SQL statement to perform a migration on the schema. An optional `down` field can be provided, this will be used when trying to do a rollback after (for instance, in case of migration failure). A new trigger is installed to capture DDL events coming from direct user manipulations (not done by pg-roll), so they are stored as a migration, getting to know the resulting schema in all cases. |

PostgreSQL zero-downtime migrations made easy.
Getting started (development)
-
Bring a development PostgreSQL up:
docker compose up -

go run . init -
Start a migration:
go run . start examples/01_create_tables.json -
Inspect the results:
psql postgres://localhost -U postgres\d+ public.* \d+ 01_create_tables.* -
(Optional) Rollback the migration (undo):
go run . rollback -
Complete the migration:
go run . complete
