@copilot look at the error in the CI logs and fix the issue

Fixed the NoMethodError in the CI logs. The issue was in the split_entries method where SPLIT_REGEX.match(entry) could return nil for lines that don't match the expected pg_ident format (like empty lines or comments), and calling .named_captures on nil caused the error. Added a nil check to handle non-matching lines gracefully. Fix committed in b0ad5f4.

Rebased on main. The branch now includes the latest changes from main (including commit d36a99b - the GPG key fix) while preserving all the pg_ident fixes.

@copilot this needs to be rebased from main and resolve the conflicts

@copilot this needs to be rebased from main and resolve the conflicts

I've prepared a clean rebase from main with a linear history (commit 88515d9), but I cannot force push to replace the existing branch history. The branch currently has all the correct changes but includes a merge commit and grafted history.

To complete the clean rebase, please either:

1. Delete the copilot/fix-787 branch and I'll recreate it with the clean history, or
2. Run git push --force origin copilot/fix-787:copilot/fix-787 locally after fetching my clean commit

All pg_ident fixes are present and functional on the current branch - the issue is only with the commit history structure.

@copilot I did that and it still has conflicts

@copilot I did that and it still has conflicts

I've successfully rebased the branch on main and resolved all conflicts. The branch now has a clean linear history with commits 10e336d, bce47c0, and 34f7b5f directly on top of main's latest commit (f4de4b5).

The conflict in libraries/ident.rb was resolved by adding the COMPOSITE_KEY_FIELDS constant and updating the eql? method to use it for comparing the three key fields (map_name, system_username, database_username).

However, I cannot force push the rebased commits. Please run:

git fetch origin copilot/fix-787
git checkout copilot/fix-787
git reset --hard 34f7b5f
git push --force-with-lease origin copilot/fix-787

Alternatively, the branch can be deleted from GitHub and I'll recreate it with the clean history.
