WaitCount stats

In the database/sql library, we have the waitCount statistic to get the total number of connections waited for. How can I obtain this statistic in pgx? In the stat() function of pgx, there is no function that returns the waitCount.

Start by reading pgx's stat() function and compare its exposed statistics with database/sql's waitCount statistic. Determine how an equivalent wait-count value could be obtained in pgx, and consider the work complete when the statistic is exposed or its supported access path is documented.
