parser problem

Is it correct that the following two statements are equal?

select "a" from foo;

select a from foo;


That results in the following problem for ecpg:

When I'm in SQL mode (that is after reading "exec sql") I do not get
quotations. But what do I do with this?

exec sql whenever sqlerror do printf("There was an error\n");

Since my lex file is almost the same as scan.l I wonder if anyone has an
idea.
