%% Version of epgsql:equery/3 that uses named statements and caches them in process dictionary
%%
%% Algorithm pseudocode is:
%% <pre>
%% stmt = cache_get(name)
%% if not stmt:
%%    stmt = parse_and_describe(name, sql)  # network roundtrip
%%    cache_put(name, stmt)
%% return bind_and_execute(stmt, params)    # network roundtrip
%% </pre>

%% Single-roundtrip version of epgsql:equery/3
%%
%% It does parse-bind-execute sequence in 1 network roundtrip.
%% The cost is that user should manually provide the datatype information for
%% each bind-parameter.
%% Another potential problem is that connection will crash if epgsql does not
%% have a codec for any of result columns. Explicit type casting may save you
%% in this case: `SELECT my_enum::text FROM my_tab'. Or you can implement the
%% codec you need.
