> MDEV-27021 Implement SHOW ANALYZE command
The patch looks good. A few cosmetic comments below.
I've played with it and it looks usable, although I would expect that SHOW
ANALYZE FORMAT=JSON would be the real killer.
For SHOW ANALYZE FORMAT=JSON, I suspect we might need to add a few fields
into it to make analysis easier (I'll elaborate later).
Let's first get SHOW ANALYZE FORMAT=JSON to work without the extra columns.
== Cosmetic comments ==
Please make sure there are no spaces at line ends. Some MariaDB developers
feel strongly about not having them. (If your edior doesn't highlight them,
"git citool" does).
At risk of stating the obvious:
* one should not remove the endspace if otherwise they are not changing the
line of code. (such "dummy" changes make it hard to look at the revision
* If one adds a line or changes an existing line, make sure the line doesnt have
the end spaces.

This will soon mean "SHOW EXPLAIN or ANALYZE or EXPLAIN FOR CONNECTION".
Does "Target is not executing an operation with a query plan" sound better?
