Can SELECT and INSERT Statements in a Stored Procedure Cause Race Conditions?

The example code shows an INSERT
followed by a SELECT
within a stored procedure, a common pattern in blog post tag management. This raises the question of race conditions, especially when multiple users might concurrently delete tags and create posts.
Database transactions are crucial for preventing such issues. Transactions group multiple database operations into an atomic unit. This means either all operations within the transaction succeed, or none do, maintaining data integrity.
PostgreSQL's transaction handling ensures that the INSERT
and SELECT
statements within a single stored procedure invocation execute serially, not concurrently. This serialization eliminates the possibility of race conditions disrupting data consistency.
