Tom Lane 0bd7305ffb Make decompilation of optimized CASE constructs more robust. ...

We had some hacks in ruleutils.c to cope with various odd transformations
that the optimizer could do on a CASE foo WHEN "CaseTestExpr = RHS" clause.
However, the fundamental impossibility of covering all cases was exposed
by Heikki, who pointed out that the "=" operator could get replaced by an
inlined SQL function, which could contain nearly anything at all.  So give
up on the hacks and just print the expression as-is if we fail to recognize
it as "CaseTestExpr = RHS".  (We must cover that case so that decompiled
rules print correctly; but we are not under any obligation to make EXPLAIN
output be 100% valid SQL in all cases, and already could not do so in some
other cases.)  This approach requires that we have some printable
representation of the CaseTestExpr node type; I used "CASE_TEST_EXPR".

Back-patch to all supported branches, since the problem case fails in all.
