[Igorgro]

Describe the bug When SQL code contains quoted constraint name, it is failed to import

To Reproduce Steps to reproduce the behavior:

1. Try to import the following code:

   CREATE TABLE books (
       id UUID NOT NULL,
       CONSTRAINT "PK_books" PRIMARY KEY (id)
   );
   

2. See error (on attached screenshot)
3. The following code does not produce error:

   CREATE TABLE books (
       id UUID NOT NULL,
       CONSTRAINT PK_books PRIMARY KEY (id)
   );
   

Expected behavior SQL script successfully imported
