* 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
* <xd> delimited identifiers (double-quoted identifiers)
* <xh> hexadecimal numeric string
* <xq> standard quoted strings
* <xe> extended quoted strings (support backslash escape sequences)

/*
* In order to make the world safe for Windows and Mac clients as well as

* sequence will be seen as two successive newlines, but that doesn't cause
* any problems. Comments that 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?
*
* XXX if you change the set of whitespace characters, fix scanner_isspace()
* to agree, and see also the plpgsql lexer.

*/
/*

* which would start a {comment}). To cover that we have {quotefail}.
* The actions for {quotestop} and {quotefail} must throw back characters
* beyond the quote proper.
*/
/* Bit string
* It is tempting to scan the string for only those characters

/* 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.
* Dash-dash comments have similar interactions with the operator rule.
*/
/*
* "self" is the set of chars that should be returned as single-character

* 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

* Other embedded escaped characters are matched explicitly and the leading
