Guides and worked examples about migrations with Ptah.
Ptah or Flyway OSS for Versioned PostgreSQL Migrations?
Run the same PostgreSQL change with Flyway OSS and Ptah, then check migration history and a live schema change.
Generate OpenMeter's View Migrations Instead of Copying Them
OpenMeter copies generated view SQL into its migrations by hand. Ptah Compat writes those statements and keeps Ent, golang-migrate and schema_om.
Bring Spark's Partitioned SQL into the Diff with Ptah
Spark keeps its partitioned-table definition outside the Ent diff. Ptah brings it into schema review while Spark keeps control of daily partitions.
Go Models and HCL Database Rules in One Ptah Schema
Declare tables with Go annotations, keep a shared PostgreSQL trigger function in HCL, and let Ptah merge both into one schema it diffs and migrates.
When Migration Releases Arrive Faster Than Reconciliation
Follow cumulative migration releases through one ordered plan, exact approval, Apply, and fresh history verification in Ptah Operator and Console.
Recover After Only Part of a MySQL Migration Commits
Observe a MySQL column addition surviving a failed index build, correct the duplicate data, and let Ptah resume at the recorded next statement.
From OCI Artifacts to Database Plans in Ptah Operator
Follow a schema or migration update from an OCI registry to a verified database change, with real Ptah Console plans and approval decisions.
Find the Transaction Blocking Your Migration
Reproduce a PostgreSQL lock timeout, identify the open transaction, release it deliberately, and verify Ptah’s migration retry and final schema.
Recover a Migration Directory After a Checksum Failure
Reproduce a changed migration file, restore its trusted bytes, and verify that Ptah preserves the deployed history and existing order.
Replace an Embedding Model and Keep a Way Back
Build a second vector generation with a real local model, compare retrieval, switch the application, and roll back when a corpus query ranks worse.
