[BUGS] plpgsql support

[Nagasubramanya L]

hello sir,    I have written a function. The language used is sql. I am not getting error if I assign an alias to a variable or if I try to declare any of the variable. I could figure out that I require support if plpgsql, but I am not able to get the suppor of this language. I have tried   CREATE PROCEDURAL LANGUAGE 'plpgsql' HANDLER plpgsql_call_handler LANCOMPILER 'PL/PGSQL'     I have even tried CREATE LANGUAGE 'plpgsql'   But I am not able to set it. What is that I should do to set up this language support.   Regards nagesh
