Suppose I want to print a debug info in parseTypeString() like this:

    + elog(DEBUG1, "parse type %s", buf.data);
     raw_parsetree_list = raw_parser(buf.data);

Rebuild the server, psql it:

    test=# set log_min_messages = debug1;
    SET
    test=# select regtypein('int4');
    DEBUG:  parse type SELECT NULL::int4
    CONTEXT:  invalid type name "int4"
     regtypein
    -----------
     integer
    (1 row)

The CONTEXT info is bogus.
