-- Migration: Fix documents table primary key to be composite (id, agent_id)
|
|
-- This is a safer approach that doesn't drop the table
|
|
|
|
-- Step 1: Drop the foreign key constraint from memory_units
|
|
ALTER TABLE memory_units DROP CONSTRAINT IF EXISTS memory_units_document_id_fkey;
|
|
ALTER TABLE memory_units DROP CONSTRAINT IF EXISTS memory_units_document_fkey;
|
|
|
|
-- Step 2: Drop the old primary key on documents
|
|
ALTER TABLE documents DROP CONSTRAINT IF EXISTS documents_pkey;
|
|
|
|
-- Step 3: Add the new composite primary key
|
|
ALTER TABLE documents ADD PRIMARY KEY (id, agent_id);
|
|
|
|
-- Step 4: Add back the foreign key constraint with the composite key
|
|
ALTER TABLE memory_units
|
|
ADD CONSTRAINT memory_units_document_fkey
|
|
FOREIGN KEY (document_id, agent_id)
|
|
REFERENCES documents(id, agent_id)
|

ON DELETE CASCADE;
