PG-222: Add benchmark support for measuring hook execution time.
...
Added a new view 'pg_stat_monitor_hook_stats' that provide execution
time statistics for all hooks installed by the module, following is a
description of the fields:
- hook: The hook function name.
- min_time: The fastest execution time recorded for the given hook.
- max_time: The slowest execution time recorded for the given hook.
- total_time: Total execution time taken by all calls to the hook.
- avg_time: Average execution time of a call to the hook.
- ncalls: Total number of calls to the hook.
- load_comparison: A percentual of time taken by an individual hook
compared to every other hook.
To enable benchmark, code must be compiled with -DBENCHMARK flag, this
will make the hook functions to be replaced by a function with the same
name plus a '_benchmark' suffix, e.g. hook_function_benchmark.
The hook_function_benchmark will call the original function and
calculate the amount of time it took to execute, than it will update
statistics for that hook.

PG-200: Add application name to the bucket ID.
...
Add application name to the key used to identify queries in the hash
table, this allows different applications to have separate entries in
pg_stat_monitor view if they issued the same query.

PG-197: Fix conflict with pg_stat_statements.
...
If pg_stat_monitor is loaded after pg_stat_statement, then it will end
up calling standard_planner function twice in the pgss_planner_hook()
function, this will trigger an assertion failure from PostgreSQL as this
function expects an untouched Query* object, and the first call to
standard_planner() done by pg_stat_statements modifies the object.
To address the problem, we avoid calling standard_planner function twice
in pg_stat_monitor, if a previous handler is installed for the hook
planner_hook, then we assume that this previous hook has already called
standard_planner function and don't do it again.
