WalkthroughThe driver now preserves connection parameter order from parsed DSNs and ChangesOrdered DSN Parameters
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The DSN ordering behavior is documented, but the current text can mislead users about when system variables are applied and may fail Markdown linting. These documentation issues should be corrected before merge. Sequence Diagram(s)sequenceDiagram

FormatDSNonly serializes the configuration; the connection setup applies the variables. This wording incorrectly attributes both operations toFormatDSN. Please distinguish applying variables from preserving their order in the formatted DSN.
* System variables are set and retained by `FormatDSN` in the order they appear in the DSN.
