Fix bugs in plpgsql and ecpg caused by assuming that isspace() would only return true for exactly the characters treated as whitespace by their flex scanners. Per report from Victor Snezhko and subsequent investigation. Also fix a passel of unsafe usages of <ctype.h> functions, that is, ye olde char-vs-unsigned-char issue. I won't miss <ctype.h> when we are finally able to stop using it. 2006-09-22 17:39:58 -04:00			`* $PostgreSQL: pgsql/src/include/parser/scansup.h,v 1.20 2006/09/22 21:39:58 tgl Exp $`

Implement a solution to the 'Turkish locale downcases I incorrectly' problem, per previous discussion. Make some additional changes to centralize the knowledge of just how identifier downcasing is done, in hopes of simplifying any future tweaking in this area. 2004-02-20 19:34:53 -05:00			`extern char scanstr(const char s);`
