Обсуждение: pgsql: Rename EXPLAIN ANALYZE's "total runtime" output to "execution ti

Rename EXPLAIN ANALYZE's "total runtime" output to "execution time".

Now that EXPLAIN also outputs a "planning time" measurement, the use of
"total" here seems rather confusing: it sounds like it might include the
planning time which of course it doesn't.  Majority opinion was that
"execution time" is a better label, so we'll call it that.

This should be noted as a backwards incompatibility for tools that examine
EXPLAIN ANALYZE output.

In passing, I failed to resist the temptation to do a little editing on the
materialized-view example affected by this change.
