I just compiled and ran my first ecpg program with indicator variables. It
needs lots of work before I can submit a patch, and I will have to increase
the major number of libecpg. Anyway, I used indicator variables with
the following syntax:

select ... into :variable:indicator

Now I checked Oracle and it accepts

select ... into :variable indicator :indicator

as well. I like this because I think this it is better readable. However,
I'm not sure which version the standard supports. Currently ecpg eaccepts
both.

Good. It looks like the standard allows both, including spaces between
":variable" and ":indicator" even when "INDICATOR" is omitted :(

No problem. That's the way it's implemented right now. I just have to do
some parser rewriting to get rid of a shift/reduce conflict when allowinf
indicators in inserts etc.
