You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: 20200929203058_is_active.go
    path of file: ./repos/dendrite/userapi/storage/postgres/deltas
    
    the code of the file until where you have to start completion: package deltas

import (
	"context"
	"database/sql"
	"fmt"
)

func UpIsActive(ctx context.Context, tx *sql.Tx) error {
	_, err := tx.ExecContext(ctx, "ALTER TABLE userapi_accounts ADD
    
func UpIsActive(ctx context.Context, tx *sql.Tx) error {
	_, err := tx.ExecContext(ctx, "ALTER TABLE userapi_accounts ADD COLUMN IF NOT EXISTS is_deactivated BOOLEAN DEFAULT FALSE;")
	if err != nil {
		return fmt.Errorf("failed to execute upgrade: %w", err)
	}
	return nil
}
