I' prefer one counter for total and one for data modifying statements.

I'd like to add a request for function call counters, presented to user
as view pg_stat_user_functions, similar in content to current
pg_stat_user_tables.

actually I'd like to have the following data gathered for each function:

call count
total call time
min running time
max running time


I'd also like a possibility to gather information about usage of locks
for both function calls and simple DML statements.
