Problem: Relation Variable

Dear Friends,

I am trying to modify the parser of the postgresql so as to print all the columns of a table (or to put them in a seperate file) when the parser meets an Insert Statement.
During the parsing, i can have the relation name ( type: char *) but i cant find the way to get from the name ("mytable1") a reference to my table (a variable of type Relation).
Could you please suggest me the appropriate function or the way to succed this?

Thank You In advance
