How to fix "Window functions are not allowed in WHERE" in PostgreSQL
Window functions like ROW_NUMBER(), RANK(), and DENSE_RANK() cannot be used directly in WHERE clauses because they are evaluated after the WHERE clause filters are processed. This limitation exists due to SQL's logical order of operations. Use a CTE (Common Table Expression) or subquery to compute window functions first, then filter in the outer query.

How to fix "malformed array literal" in PostgreSQL
The "malformed array literal" error in PostgreSQL occurs when array values are provided in incorrect syntax. PostgreSQL requires arrays to be enclosed in curly braces with proper comma separation and quoted elements. Common causes include using JSON syntax instead of PostgreSQL syntax, missing quotes around special characters, and data type mismatches. Fixing requires proper array formatting according to PostgreSQL conventions.

How to fix "cannot truncate table" because of foreign key references in PostgreSQL
This error occurs when you try to TRUNCATE a table that is referenced by another table through a foreign key constraint. TRUNCATE is much faster than DELETE but cannot proceed if child tables have references. Use CASCADE to truncate all related tables together, truncate tables in dependency order, or temporarily disable constraints.
