just another standards question - Mailing list pgsql-hackers

I'm about finished with indicator variables. They seem to work well with
output variables as well as with input variables in insert statements.

Now the one question: Informix and Sybase have three different settings for
indicator variables:

-1 means value is null
0 means value is okay
> 0 means value is okay, but string was truncated to n bytes

I tried Oracle but apparently they just use 0 and -1. Does the standard say
anything about this?

BTW is this SQL standard on-line anywhere? A WWW page maybe?
