What is defined explicitly:

#ifdef  YY_READ_BUF_SIZE
#undef  YY_READ_BUF_SIZE
#endif
#define YY_READ_BUF_SIZE    MAX_PARSE_BUFFER

(these strings are repeated twice :)

...
char literal[MAX_PARSE_BUFFER];

...
<xq>{xqliteral} {                if ((llen+yyleng) > (MAX_PARSE_BUFFER - 1))                    elog(ERROR,"quoted
stringparse buffer of %d chars
 
exceeded",MAX_PARSE_BUFFER);                memcpy(literal+llen, yytext, yyleng+1);                llen += yyleng;
     }
 

Seems that limits are everywhere ;)
