commit    b640d231230c486ed1b2b94167478fc8ced5dcff
Author:   Tom Lane <tgl@sss.pgh.pa.us>

    Documentation fix: sum(float4) returns float4, not float8.
    
    The old claim is from my commit d06ebdb8d3425185d7e641d15e45908658a0177d of
    2000-07-17, but it seems to have been a plain old thinko; sum(float4) has
    been distinct from sum(float8) since Berkeley days.  Noted by KaiGai Kohei.
    
    While at it, mention the existence of sum(money), which is also of
    embarrassingly ancient vintage.
