Better scrolling of long explain plans on explain.depesz.com

Thanks to some discussion on Slack, and work by Alexandre Felipe viewing of large explains will be now a bit easier.

You can see it, for example, in this explain.

First of all, when you scroll down, the column headers stay in place. Plus – you can always see the horizontal scrollbar to see the rest for really long node descriptions.

Thanks a lot, I appreciate the work.

New Pg::Explain and explain.depesz.com

Just now pushed new version of Pg::Explain Perl library that is handling parsing for explain.depesz.com.

There have been many changes, but the short summary is:

  • Fix display of heap fetches from json (https://gitlab.com/depesz/explain.depesz.com/issues/15)
  • Move global data (planning/execution/total time, trigger info) from top_node to explain object itself
  • Add method to easily get real total, wall-clock, runtime of query.
  • Add Pg::Explain::Analyzer, so far it can extract node types and their “paths"
  • Add scripts to run perltidy, start development tmux env, and explain schema dumper
  • Fix handling of parallel queries (hopefully)
  • Remove edge-case deep recursion error
  • Speed optimization for large explains

Hopefully it will not break anything for you 🙂

And as a final note: explain.depesz.com has been used to add almost 740kplans (out of which 120k were deleted). Currently database contains over 311k public (visible in history), not deleted, plans.
