...one of the most highly regarded and expertly designed C++ library projects in the world. — Herb Sutter and Andrei Alexandrescu, C++ Coding Standards

Adds a close statement stage.

pipeline_request&
add_close_statement(
    statement stmt);

Creates a stage that closes a prepared statement. The resulting stage has effects equivalent to conn.close_statement(stmt).

Strong guarantee. Memory allocations may throw.

The passed statement should be valid (stmt.valid() == true).
