SQLite `generate_series` Precision Bug, PostgreSQL Pagination Tuning, & Large Table Replication

Short summary

SQLite's generate_series exhibits a floating-point precision bug with strict REAL bounds near 2^53 due to optimizer rounding—critical for scientific and financial applications. PostgreSQL's naive OFFSET pagination degrades severely on deep pages; keyset (cursor-based) pagination uses indexed column values from the previous row to eliminate row scanning and maintain consistent performance. Boundary slicing divides large table replication into indexed chunks, enabling parallel processing, easier failure recovery, and minimal source database impact.

• •SQLite generate_series has floating-point precision bugs with REAL bounds near 2^53 due to incorrect optimizer rounding
• •PostgreSQL OFFSET pagination is slow on deep pages; keyset pagination using indexed cursor values solves this scalably
• •Boundary slicing divides large table replication into indexed chunks for parallel processing and resilient recovery
