Need to do SPI_push/SPI_pop around expression evaluation in plpgsql.
We must do this in case the expression evaluation results in calling
another plpgsql function (or, really, anything using SPI). I missed
the need for this when I converted exec_cast_value() from doing a
simple InputFunctionCall() to doing ExecEvalExpr() in commit 1345cc67b.
There is a SPI_push_conditional in InputFunctionCall(), so that there
was no bug before that.
Per bug #14414 from Marcos Castedo. Add a regression test based on his
example, which was that a plpgsql function in a domain check constraint
didn't work when assigning to a domain-type variable within plpgsql.
