Module diff 

Pure-function diff over the IR.

diff(target, source) returns a ChangeSet describing every structural difference between two Catalog snapshots. No SQL is generated here — that is the job of phases 5+ (planner, rewrites).

Direction

diff(target, source) describes the changes needed to take the target catalog and turn it into the source catalog. In pgevolve terminology, the “target” is the live database and the “source” is the desired state declared in *.sql files; running the resulting plan converges target to source.

Modules

aggregates

Differ for Catalog::aggregates.

casts

Differ for Catalog::casts.

change

Change — one entry in a ChangeSet.

changeset

ChangeSet — an unordered collection of ChangeEntry values, plus two observation accumulators for downstream lint rules.

cluster

Cluster diffing.

collations

Differ for collations. Per-collation granular diff:

columns

Column-level diffing inside an AlterTable.

constraints

Constraint-level diffing inside an AlterTable.

default_privileges

Diff ALTER DEFAULT PRIVILEGES rules.

destructiveness

Destructiveness — risk classification attached to every diff change.

event_triggers

Differ for Catalog::event_triggers.

extensions

Differ for Catalog::extensions.

grants

Shared grant-list diffing with lenient drift policy.

indexes

Index-level diffing.

owner_grants

The single definition of the per-object owner + grants diff sequence.

owner_op

Catalog-object reference (CatalogObjectRef) and the uniform owner-change op (AlterObjectOwner) shared by the grant and owner diffs.

policies

Per-table policy diffing + RLS toggles.

publications

Differ for publications. Pair by name; per-publication granular diff.

reloptions

Sparse-delta diffing for storage reloptions. Lenient policy: source None always means “skip”; catalog values not in source surface as unmanaged-reloption lint, never RESET.

routines

Diff functions and procedures.

schemas

Schema-level diffing.

sequence_op

SequenceOp — per-sequence field updates.

sequences

Sequence-level diffing.

statistics

Differ for statistics. Per-statistic granular diff:

subscriptions

Differ for subscriptions. Pair by name; per-subscription granular diff.

table_op

TableOp — per-table column / constraint operations.

tables

Table-level diffing.

triggers

Differ for Catalog::triggers.

ts_configurations

Differ for Catalog::ts_configurations.

ts_dictionaries

Differ for Catalog::ts_dictionaries.

types

Diff user-defined types (enums, domains, composites).

views

View / MV diff and OR-REPLACE compatibility.

Functions

diff

Compute the changes needed to converge target toward source.
