Subject: [PATCH] Fix seed SQL execution to handle multiple statements
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

PostgreSQL prepared statements don't support multiple commands.
Split SQL file into individual statements and execute each one,
handling string literals and comment-only blocks properly.
