explain cost check

See original GitHub issue

Would be good to have ability to setup upper bound of explain cost. If explain cost more than this upper bound for particular query, error occured about heavy sql. Explain cost can be set in tsconfig.json for tsserver and as cli flag for cli tool.

Example:

Limit  (cost=0.00..50000.55 rows=1000000 width=341) (actual time=0.003..0.003 rows=0 loops=1)
  ->  Seq Scan on car  (cost=0.00..12.20 rows=220 width=341) (actual time=0.002..0.002 rows=0 loops=1)
Planning Time: 0.058 ms
Execution Time: 0.015 ms

50000.55 so heavy, max upper bound is 10000
