Debug slow Postgres queries

Write SQL in Vim, format, and run until the query is correct.

If it's slow, add this to the top of the file:

EXPLAIN (ANALYZE, COSTS, VERBOSE, BUFFERS, FORMAT JSON)

Then, run:

:!psql -qAt -d db_name -f % | pbcopy

Paste into http://tatiyants.com/pev/#/plans/new and delete the trailing line to make it valid JSON:

Time: 1111.111 ms (00:01.111)

The output is an interactive visualization that makes it easy to identify which parts of the query are slowest, largest, and costliest.
