Hmmm, I wonder how many languages I will learn while dealing with PostgreSQL. What about performance of pltcl compared to C. I wonder if I just do all my work using C-functions, because I know C very well and don't want to reach the next limit which I will possibly face when using pltcl. I would really like to write all my functions in SQL or PLPGSQL. If this is really impossible (I just wonder if the construct above could really not be implemented???), I would prefer C over other languages, if there are no real drawbacks. Kind regards Andreas.
