Increase rounding precision in uncompressed_size test to reduce flakiness The test was rounding uncompressed heap and index sizes to the nearest 100,000 bytes, but this was still too precise and subject to variance from PostgreSQL's storage layer (page alignment, tuple padding, etc.). The nightly failure showed heap_size rounding from ~5,250,000 to 5,300,000 instead of the expected 5,200,000. Changing to round to the nearest 1,000,000 bytes provides more tolerance for these natural variations while still validating that the size calculations are in the correct ballpark. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
