 * OK, here is a short description of lex/flex rules behavior.
 * The longest pattern which matches an input string is always chosen.
 * For equal-length patterns, the first occurring in the rules list is chosen.
 * INITIAL is the starting state, to which all non-conditional rules apply.
 * Exclusive states change parsing rules while the state is active.  When in
 * an exclusive state, only those rules defined for that state apply.
 *
 * We use exclusive states for quoted strings, extended comments,
 * and to eliminate parsing troubles for numeric strings.
 * Exclusive states:
 *	<xb> bit string literal
 *	<xc> extended C-style comments - thomas 1997-07-12
 *	<xd> delimited identifiers (double-quoted identifiers) - thomas 1997-10-27

/* C-style comments
 *
 * The "extended comment" syntax closely resembles allowable operator syntax.
 * The tricky part here is to get lex to recognize a string starting with
 * slash-star as a comment, when interpreting it as an operator would produce
 * a longer match --- remember lex will prefer a longer match!	Also, if we
 * have something like plus-slash-star, lex will think this is a 3-character
 * operator whereas we want to see it as a + operator and a comment start.
 * The solution is two-fold:
 * 1. append {op_chars}* to xcstart so that it matches as much text as
 *	  {operator} would. Then the tie-breaker (first matching rule of same
 *	  length) ensures xcstart wins.  We put back the extra stuff with yyless()
 *	  in case it contains a star-slash that should terminate the comment.
 * 2. In the operator rule, check for slash-star within the operator, and
 *	  if found throw it back with yyless().  This handles the plus-slash-star
 *	  problem.
 * SQL92-style comments, which start with dash-dash, have similar interactions
 * with the operator rule.
 */
/*
 * "self" is the set of chars that should be returned as single-character
 * tokens.	"op_chars" is the set of chars that can make up "Op" tokens,
 * which can be one or more characters long (but if a single-char token
 * appears in the "self" set, it is not to be returned as an Op).  Note
 * that the sets overlap, but each has some chars that are not in the other.
 *
 * If you change either set, adjust the character lists appearing in the
 * rule for "operator"!
 */
/* we no longer allow unary minus in numbers.
 * instead we pass it separately to parser. there it gets
 * coerced via doNegate() -- Leon aug 20 1999
 */
/*
 * In order to make the world safe for Windows and Mac clients as well as
 * Unix ones, we accept either \n or \r as a newline.  A DOS-style \r\n
 * sequence will be seen as two successive newlines, but that doesn't cause
 * any problems.  SQL92-style comments, which start with -- and extend to the
 * next newline, are treated as equivalent to a single whitespace character.
 *
 * NOTE a fine point: if there is no newline following --, we will absorb
 * everything to the end of the input as a comment.  This is correct.  Older
 * versions of Postgres failed to recognize -- as a comment if the input
 * did not end with a newline.
 *
 * XXX perhaps \f (formfeed) should be treated as a newline as well?
 */
/*
 * SQL92 requires at least one newline in the whitespace separating
 * string literals that are to be concatenated.  Silly, but who are we
 * to argue?  Note that {whitespace_with_newline} should not have * after
 * it, whereas {whitespace} should generally have a * after it...
 */
/* some stuff needed for ecpg */

/*
 * Quoted strings must allow some special characters such as single-quote
 *	and newline.
 * Embedded single-quotes are implemented both in the SQL92-standard
 *	style of two adjacent single quotes "''" and in the Postgres/Java style
 *	of escaped-quote "\'".
 * Other embedded escaped characters are matched explicitly and the leading
 *	backslash is dropped from the string. - thomas 1997-09-24
 * Note that xcstart must appear before operator, as explained above!
 *	Also whitespace (comment) must appear before operator.
