Support deparsing "CASE expr WHEN ... END" clause

[Papierkorb]

Hi,

I found another syntax case where deparse forgot to output something. It's the expression in CASE expr WHEN ... END, the docs call it "simple CASE":

§9.17.1 CASE

There is a “simple” form of CASE expression that is a variant of the general form above:

CASE expression
    WHEN value THEN result
    [WHEN ...]
    [ELSE result]
END

The first expression is computed, then compared to each of the value expressions in the WHEN clauses until one is found that is equal to it. If no match is found, the result of the ELSE clause (or a null value) is returned. This is similar to the switch statement in C.

I was rather confused why the AST I built didn't have the expression lul..
