refactor(db/pgsql): Revert SQL queries, lower column casing for PGSQL

Reverts SQL query identifier escaping to simplify queries and improves overall readability by using lowercase column names.

Enhances maintainability and alignment with database conventions by adopting a uniform casing scheme across all SQL operations.

Removes unnecessary complexity in query construction, streamlining the database operations performed within the application.
