-- Migration: 001_initial_schema.sql
-- Description: Initial database schema with example items table
-- To customize: Rename tables/columns and add your own migrations

-- Create items table (example)
CREATE TABLE IF NOT EXISTS items (
    id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
    name VARCHAR(255) NOT NULL,
    description TEXT,
    status VARCHAR(50) NOT NULL DEFAULT 'active',
    metadata JSONB,
    created TIMESTAMPTZ NOT NULL DEFAULT NOW(),
    modified TIMESTAMPTZ NOT NULL DEFAULT NOW()
);

-- Create index on status for faster filtering
CREATE INDEX IF NOT EXISTS idx_items_status ON items(status);

-- Create index on created for sorting
CREATE INDEX IF NOT EXISTS idx_items_created ON items(created);

-- Optional: Trigger to auto-update modified timestamp
CREATE OR REPLACE FUNCTION update_modified_column()
RETURNS TRIGGER AS $$
BEGIN
    NEW.modified = NOW();
    RETURN NEW;
END;
$$ language 'plpgsql';

CREATE OR REPLACE TRIGGER update_items_modtime
    BEFORE UPDATE ON items
    FOR EACH ROW
    EXECUTE FUNCTION update_modified_column();

-- Add table comment
COMMENT ON TABLE items IS 'Example items table - replace with your own schema';
