Hi Meskes-san, Takahashi-san

I will try to implement it with the Idea-2 that doesn't use PQprepare() and
Takahasi-san's following idea.

But I will probably be late because I don't understand parse.pl very well.
I think that the following rule is made by parse.pl.
PreparableStmt:
SelectStmt
{
is_in_preparable_stmt = true; <--- I want to add it.
$$ = $1;
}
| InsertStmt
.....
The above variable is used in ecpg.trailer.
ecpg_param: PARAM {
if(is_in_preparable_stmt)
$$ = mm_strdup(replace_dollar_to_something());
else
$$ = make_name();
} ;
I will use @1 instend of $$1 because the replacing is almost same as the existing replacing function in ecpglib.
Is it good?
