Re: plpgsql.. SELECT INTO ... WHERE FIELD LIKE

Try:  SELECT INTO RS ID FROM CUSTOMER WHERE FIRSTNAME LIKE KEYWORD || ''%'' LIMIT 1;

You append KEYWORD and a '%' together using ||.  You need to use
doubled quotes inside the quoted environment; one gets stripped off so
that the stored procedure will contain the query
  SELECT INTO RS ID FROM CUSTOMER WHERE FIRSTNAME LIKE KEYWORD || '%'' LIMIT 1;

C is almost a real language. (see assembler) Even the name sounds like
it's gone through  an optimizing  compiler.  Get  rid of  all of those
stupid brackets and we'll talk. (see LISP)
