Thank you for committing the 0002 part of the patch!

I've looked at your 0001-to-timestamp-format-checking-v5.patch. It seems nice to me. I suppose it is necessary to fix is_char_separator() declaration. from: static bool is_char_separator(char *str); to: static bool is_char_separator(const char *str); Because now in parse_format() *str argument is const. I attached new version of the patch, which fix is_char_separator() declaration too. Sorry for confusing! -- Artur Zakirov Postgres Professional: http://www.postgrespro.com Russian Postgres Company
