SQLite generate_series Precision Bug, PostgreSQL Pagination Tuning, & Large Table Replication Today's Highlights This week, we delve into a critical SQLite bug affecting generate_series with real bounds and explore advanced PostgreSQL pagination strategies for consistent performance across large datasets. Additionally, we highlight an efficient data replication technique using boundary slicing for very large tables. Post: generate_series returns incorrect results for strict REAL bounds near 2^53 due to rounding in constraint pushdown (SQLite Forum) Source: https://sqlite.org/forum/info/6e6cf9054bea2b1d1d292c46e443b55c2dcd1c7e44586ff4a3e69488aed5b3da This SQLite forum post details a significant bug in the generate_series table-valued function, specifically when used with strict REAL bounds close to 2^53 . The issue, observed in versions like 3.52 and 3.53, stems from an incorrect rounding operation during constraint pushdown optimization, leading to unexpected and inaccurate results.…
