Dear Andrei,
I think the idea is good because the pg_stat_statements_info view cannot distinguish
whether the specific statement is deallocated or not.
But multiple calling of GetCurrentTimestamp() may cause some performance issues.
How about adding a configuration parameter for controlling this feature?
Or we don't not have to worry about that?

I think {} is not needed here.
