My point is not whether 2 billion is a better number than 4 billion as a maximum value. My point is that wraparound of signed int is, I think, not even defined in C, whereas wraparound of unsigned int is well defined. cur_line should be declared as unsigned int. I don't trust that INT_MAX+2 arithmetic. Please don't use cur_line as a name for a global variable. Something like PSQLLineNumber seems more appropriate if it's going to be exposed through prompt.h. However, note that MainLoop() keeps state in local variables and notes that it is reentrant; what happens to your cur_line when a file is read by \i and similar? I wonder if it should be part of PsqlScanStateData instead ... -- Álvaro Herrera http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
